Weed Data Collection Manual SECTION TWO TECHNICAL DATA DESCRIPTION

DEPARTMENT OF LAND RESOURCE MANAGEMENT

Introduction

Section two of the Weed Data Collection Manual provides technical data descriptions, including metadata, data dictionary and comprehensive weed species tables, and is intended to assist weed data managers. The information meets data standards obligations, informs weed database design, and assists software developers and power users to create their own electronic tools for the collection of weed data.

The metadata section describes characteristics of the NT weed dataset as a whole and contains a Metadata ID.

The Data Dictionary describes each of the values for the data attributes, data type, set values, and design notes related to that attribute. Unless indicated, the attribute descriptions are the same for ALL geometry types. (ie points, polylines or polygons). The specified values must be entered into the datasets exactly as written. Text values should be written using proper case. eg, write Yes. Do not write YES (upper case) or yes (lower case).

Attribute type Details

Core attributes These are the minimum requirements to establish a reliable, valid record with useful information for operational and strategic weed planning.

Recommended attributes The Weed Management Branch recommends collection of this data to improve and evaluate the effectiveness of control effort and weed impacts over time.

Optional attributes Optional attributes are useful for operational planning within an organisation, for particular project requirements or for property scale weed planning. Records submitted to the Weed Management Branch do not require optional attributes but they will be retained by the Branch if submitted.

The weed species listing contains a comprehensive list of Northern Territory weeds and should be taken as a guide to how to represent weed species names internally within weed databases.

Core Attributes

1. Data record 1.1 Field name ID Alias * INDEX

Field parameters Autonumbered integer Definition Unique record identifier, database generated. Example 1 Notes Number is generated by hosting software and may be subject to re-indexing, cannot be relied upon as a reference to a record. Database design The ID field is a surrogate key for compound key GENUS_SPP + DATE + LAT_94 + LONG_94.

A surrogate key was used for reasons of performance, limitations of ESRI software and the reduced expertise required to join single field primary keys over compound keys.

1.2 Field name SITE_ID Alias SITE IDENTIFIER

Field parameters Text (string), 15 characters Definition Waypoint ID or other similar source identifier for this record applied by the observer. Example WAYPOINT01 Notes This is not a unique identifier.

The intention of this field is to assist in tracing a record back to its field observation source. Blank values can be entered. Null or empty string value designates no data value. Note that some software (including FME) is sensitive to null vs empty values and will require handling at application level.

1.3 Field name SITE_MON Alias SITE MONITORING

Field parameters Text (string), 15 characters Definition Identifies spatially unique site with the intent of revisiting the same place in order to monitor progress. Example Daly0001 Notes This is not a unique identifier.

Ideally a monitoring protocol should be used in association with a site identified by this field. Blank values can be entered. Null or empty string value designates no data value. Note that some software (including FME) is sensitive to null vs empty values and will require handling at application level.

* Note : Alias is an alternative full name for fields which can be used in systems that permit full attribute names ie : not ESRI shapefile.

Core Attributes (continued) 2. Name of weed

2.1 Field name WEED_NAME Alias COMMON NAME Field parameters Text (string), 40 characters Definition Common name of the weed species. Example Mimosa Set values Required. Refer to Section 2 NT Weed Species List for correct spelling conventions. Notes Blank values are applicable, null or empty string value designates no data value. Note that some software (including FME) is sensitive

to null vs empty values and will require handling at application level. Values are case sensitive; Title case is used on the list Section 2 NT Weed Species List this is to aid readability in mobile applications. Conventions apply to common names, see Section 2 NT Weed Species List for details.

2.2 Field Name GENUS_SPP Alias GENUS SPECIES

Field Parameters Text (string), 60 characters Definition Scientific or Botanical name of the weed species ie Genus species. Example Mimosa pigra Set Values Required. Refer to Section 2 NT Weed Species List for correct spelling conventions. Notes Blank values are not acceptable.

Values are case sensitive. Database design This field forms part of compound key GENUS_SPP + DATE + LAT_94 + LONG_94 for which ID field is a surrogate key.

3. When was the site assessed?

3.1 Field name DATE_REC Alias DATE RECORDED Field parameters Date Definition The date of the recorded observation. Note, record in format 1/1/2011 if the exact day/month is unknown. Format DD/MM/YYYY Example 12/03/2005 Notes Blank values are not acceptable. Record in format 1/1/2011 if the exact day/month is unknown. Record in format 1/1/1900 if the date

is unknown. Database design This field forms part of compound key GENUS_SPP + DATE + LAT_94 + LONG_94 for which ID field is a surrogate key.

Core Attributes (continued) 4. Co-ordinate position 4.1 Field name LAT_G94 Alias LATITUDE

Field parameters Number (Double) Definition The latitude (Y coordinate, determines North - South), identifying the location of the weed infestation site. This must be entered in

Decimal Degrees ideally to 5 decimal places (equivalent to 1 metre on the ground). The location should be recorded in the centre of the weed infestation, if possible. All data is stored using the datum GDA94 (Geocentric Datum of Aust 1994). For POLYLINE or POLYGON data the latitude is calculated for the midpoint of the line or centroid.

Example -13.02345 Notes Blank values are not acceptable. Database design This field forms part of compound key GENUS_SPP + DATE + LAT_94 + LONG_94 for which ID field is a surrogate key.

4.2 Field name LONG_G94 Alias LONGITUDE

Field parameters Number (Double) Definition The longitude (X coordinate, determines East - West), identifying the location of the weed infestation site. This must be entered in

Decimal Degrees ideally to 5 decimal places (equivalent to 1 metre on the ground). The location should be recorded in the centre of the weed infestation, if possible. All data is stored using the datum GDA94 (Geocentric Datum of Aust 1994). For POLYLINE or POLYGON data the latitude is calculated for the midpoint of the line or centroid.

Example 131.45761 Notes Blank values are not acceptable. Database design This field forms part of compound key GENUS_SPP + DATE + LAT_94 + LONG_94 for which ID field is a surrogate key.

Core Attributes (continued) 4. Co-ordinate position (continued)

4.3 Field name REC_METHOD Alias RECORDING METHOD

Field parameters Text (string), 25 characters Definition Method used to define the weed infestation location. Current set values should be used wherever possible, historical set values have

been retained for compatibility with existing record. Set values Current : Aerial spray

Aerial survey Differential GPS High precision GPS Itracker device Onscreen digitised Low precision GPS Not recorded Prior record Corridor survey

Retired : Averaged GPS Hand drawn on map Single GPS Topo map ref

Notes Blank values are not acceptable. Some values within the set list are redundant ie: different list values represent the same level of accuracy. They are retained to allow users to enter values that are more intuitive than if they were listed by strict functional categories. Use of retired values is discouraged but records should not be rejected on this basis. This field renames the PRECISION field in the previous standard; this is to avoid confusion with existing formal definitions for the term ‘precision’ used in surveying and related fields.

Core Attributes (continued) 5. Who assessed it? 5.1 Field name RECORDER Alias RECORDER

Field parameters Text (string), 40 characters Definition The name of the person responsible for capturing the weed data information. In the case of supervised teams the supervisor’s name

should be entered against the data. Check previous submitted entries to maintain consistency of name. Example Phil Hickey Notes Field RECORDER and ORG_NAME must not both be blank ie: RECORDER & ORG_NAME <> “”.

Where blank values are applicable, null or empty string value designates no data value. Note that some software (including FME) is sensitive to null vs empty values and will require handling at application level. Values are case sensitive.

Database design The relationship between RECORDER and ORG_NAME appears anomalous with 3rd normal form. However, persons recording data may do so for different organisations. Care should be taken this is handled correctly at application level and with direct data entry.

5.2 Field name ORG_NAME Alias ORGANISATION NAME

Field parameters Text (string), 50 characters Definition The name of the organisation submitting the weed data information. Check previously submitted entries to maintain consistency of

name of the organisation. Where the organisation is unknown or an individual is submitting data the value should be entered as blank. Example Weed Management Branch Notes Field RECORDER and ORG_NAME must not both be blank ie: RECORDER & ORG_NAME <> “”.

Where blank values are applicable, null or empty string value designates no data value. Note that some software (including FME) is sensitive to null vs empty values and will require handling at application level. Values are case sensitive.

Database design The relationship between RECORDER and ORG_NAME appears anomalous with 3rd normal form. However, persons recording may do so for different organisations. Care should be taken this is handled correctly at application level and with direct data entry.

Core Attributes (continued) 6. Infestation size Caution: The measure of infestation area is different for point, line and polygon data sets.

Point only, use WIDTH_M for line datasets and SIZE_M2 for polygon datasets 6.1a Field name SIZE_DIA_M Alias SIZE DIAMETER

Field parameters Number (Integer), Short Definition Approximate diameter of the weed infestation area (using metres). Set values 5

20 50 100 200 (aerial survey only)

Notes Blank values are not acceptable; data administrators should force all ‘no data’, blank or null values to sentinel value -1. Care should be taken not to include the sentinel value in summary statistics.

(Line only, use SIZE_DIA_M for point datasets and SIZE_M2 for polygon datasets 6.1b Field name WIDTH_M Alias WIDTH METRES

Field parameters Number (Integer), Short Definition Approximate width of a linear weed infestation area (using metres). Set values 5

20 50 100

Notes Blank values are not acceptable; data administrators should force all ‘no data’, blank or null values to sentinel value -1. Care should be taken not to include the sentinel value in summary statistics.

- Polygon only, use SIZE_DIA_M for point datasets and WIDTH_M for line datasets

6.1c Field name SIZE_M2 Alias SIZE M2 Field parameters Number (Integer), Long Definition Calculated area of a polygon defined weed infestation area (using metres squared). Notes Blank values are not acceptable; data administrators should force all ‘no data’, blank or null values to sentinel value -1.

Care should be taken not to include the sentinel value in summary statistics.

Core Attributes (continued) 7. Infestation description

7.1 Field name DENS_CAT Alias DENSITY CATEGORY Field parameters Number (Integer), Short Definition Weed density is the estimated area occupied by the weed expressed as a percentage of the designated site area size, whether

assessed by: surface area occupied (for aquatic plants, smaller grasses and herbs) projected canopy cover (for larger grasses, vines, tall shrubs and trees

This information can illustrate changes in severity of weed infestations across the landscape over time. Ref: A field manual for surveying and mapping nationally significant weeds, page 20

Set values CLASS DESCRIPTION (11 Density classes or categories) 1. Absent 2. < 1% 3. 1 – 10% 4. 11 – 50% 5. >50% 6. Present but density unknown 7. Not known 8. Not assessed 9. Aquatic – scattered 10. Aquatic – 100% cover 11. Eradicated and monitored

Notes Where sites have been successfully treated but standing vegetation that can be positively identified remains ie: dead trees, bushes, or remnants of grass, the remaining dead vegetation should be assessed in the density category score. Blank values are not acceptable; data administrators should force all ‘no data’, blank or null values to entry value 8 (Not Assessed).

Core Attributes (continued) 7. Infestation description (continued)

7.2 Field name TREATMENT Alias TREATMENT

Field parameters Text (string), 40 characters Definition What was the treatment applied today, if any? Set values No treatment

Unknown Treated Foliar spray Residual application Basal bark Cut stump Stem injection Aerial spray Slashed or cut Burn Hand pull Shaded or covered Combination treatment

Notes This field should best describe the treatment applied to the weed point area on the day the record is taken. Database design When TREATMENT is used with optional fields SURFACTANT, CHEM_TRADE, CHEM_CONC, and ADJUVANTS the attribute

causes the table to fail 3rd normal formal form due to transitive dependency ie: ‘attribute is dependent on the key and only on the key’.

The impact of the associated anomalies is considered minor in the context of the weeds database as records are not typically deleted or modified in regular usage.

Administrators are advised to check field TREATMENT against the value of these fields for addition anomalies before adding records, and to periodically check TREATMENT against these field values for the entire dataset. Application level controls can be used to reduce the number of addition anomalies.

Recommended Attributes These fields are not core. Data administrators can decide if this field is relevant to their organisation’s needs and may choose not to include it in their data sets. The designation ‘Recommended Attribute’ indicates that the Weed Management Branch recommends that this field will be required by the majority of organisations for effective weed management.

8. Infestation description

8.1 Field name PROJECT Alias PROJECT

Field parameters Text (string), 150 characters Definition Project description, where work is carried out for a specific project Example Daly catchment strategic mimosa control Notes Care must be taken with project names to ensure they are entered consistently for each record, apply application level controls where

possible. Actual project names may contain punctuation characters which cause difficulties for GIS or database processing, users should be made aware of these restrictions and application level controls applied where possible. This field may cause update, addition and deletion data anomalies, apply application level controls where possible.

Database design Actual project names frequently contain compounds of species, activity and date which causes the table to fail 1st normal formal form ie: ‘attribute contains only atomic values, and the value of each attribute contains only a single value from that domain’. A strong user case exists for associating weed records with the project that enabled their recording. The convenience of seeing project information on the same row as the weed record without the complexity of joined tables is cited as the rationale for this anomaly. Organisations with a strong information processing capacity should consider use of separation of tables to remove this anomaly. Users specifically required sufficient field length to store full actual project names in their entirety, organisations with less complex project requirements may shorten this field to more conventional lengths.

8.2 Field name SEEDLINGS Alias SEEDLINGS

Field parameters Text (string), 12 characters Definition Are seedlings present at the site? Set values Yes

No Unknown Not recorded

Recommended Attributes (continued) 8. Infestation description (continued)

8.3 Field name JUVENILES Alias JUVENILES

Field parameters Text (string), 12 characters Definition Are juveniles present at the site?

Juvenile plants are past the seedling stage but have not as yet produced seed or reached a size or maturity to be capable of producing seed.

Set values Yes No Unknown Not recorded

Notes Visible assessment of juvenile plants present at the site. Dead juveniles should be recorded as present.

8.4 Field name ADULTS Alias ADULTS

Field parameters Text (string), 12 characters Definition Are adult plants present at the site?

Adult plants include any plants which have produced seed. Adult plants also include any plant that has reached a size or appearance of maturity of being ‘fully grown’ or likely to produce seed.

Set values Yes No Unknown Not recorded

Database design The fields ADULTS and SEED_PRES causes the table to fail 3rd normal formal form due to transitive dependency ie: ‘attribute is dependent on the key and only on the key’. The impact of the associated anomalies is considered minor in the context of the weeds database as records are not typically deleted or modified in regular usage. Administrators are advised to check for addition anomalies before adding records, application level controls can be used to reduce the number of addition anomalies.

Recommended Attributes (continued) 8. Infestation description (continued)

8.5 Field name SEED_PRES Alias SEED_PRESENT

Field parameters Text (string), 12 characters Definition Are seeds visible at the site?

Record ‘Yes’ when seeds are visible at the site, either on plants, or fallen. Where evidence of seeding exists such as seed pods or seedlings but no actual seeds are visible the value ‘No’ should be recorded.

Set values Yes No Not assessable Not recorded

Database design The fields ADULTS and SEED_PRES causes the table to fail 3rd normal formal form due to transitive dependency ie: ‘attribute is dependent on the key and only on the key’. The impact of the associated anomalies is considered minor in the context of the weeds database as records are not typically deleted or modified in regular usage. Administrators are advised to check for addition anomalies before adding records, application level controls can be used to reduce the number of addition anomalies.

Recommended Attributes (continued) 8. Infestation description (continued) 8.6 Field name PAST_TREAT Alias PAST_TREATMENT

Field parameters Text (string), 12 characters Definition Are impacts from previous treatments visible at the site? Set values Yes


Notes When the site has been visibly impacted by past treatment methods record ‘Yes’. If a treatment was known to be applied but its impact is not visibly noticeable then record ‘No’. If uncertain whether poor plant condition is the result of past treatment, or is a consequence of water stress, dieback, or other adverse environmental factors then record ‘Unknown’. Also record ‘Unknown’ if the site is not assessable due to fire, flooding or other disturbance. Further details of the impact of control can be recorded in optional fields TREAT_MON and SITE_COND. For mechanical treatments such as slashing, record ‘Yes’ only while the treatment continues to mitigate the impact of the weed. Once the weed has regrown to nuisance level it should be recorded as ‘No’. For fire impacts, only record ‘Yes’ where the impact is a result of weed management prescribed fire, record ‘No’ for wildfire or other burning practices such as fuel reduction. Do not record the impact of treatments applied on the date of the record (today) in this field.

Database design This field replaces TREAT_WHEN field in the previous standard and corrects the 2nd normal form failure where the TREAT_WHEN value was not dependent on the entire compound key. This loosely translates to the concept that each individual weed record must refer to a specific instance of a weed in one time and place. Field PAST_TREAT when used with optional attributes TREAT_MON causes the table to fail 3rd normal formal form due to transitive dependency ie: ‘attribute is dependent on the key and only on the key’. The impact of the associated anomalies is considered minor in the context of the weeds database as records are not typically deleted or modified in regular usage. Administrators are advised to check field TREAT_MON for addition anomalies before adding records, application level controls can be used to reduce the number of addition anomalies.

Recommended Attributes (continued) 9. Additional area information 9.1 Field name HERBICIDE Alias HERBICIDE

Field parameters Text (string), 40 characters Definition What was the active ingredient(s) of the herbicide applied today, if any? Examples No treatment

Not recorded Glyphosate Glyphosate 360gL

Notes This field renames the TREAT_CHEM field in the previous standard, this is to clarify the purpose of the field as recording active herbicide ingredients rather than brand names, adjuvants or other additives which are handled in other fields.

9.2 Field name YEAR Alias YEAR

Field parameters Text (string), 4 characters Definition The year the weed data was recorded. Format YYYY Examples 2006 Notes Blank values are not acceptable.

Record as value ‘1900’ if the year is unknown. Database design The field YEAR and DATE_REC causes the table to fail 3rd normal formal form due to transitive dependency ie: ‘attribute is dependent

on the key and only on the key’. The relative ease of recalculating this field combined with the strong user case for being able to group and use weed data by year without needing field calculation skills is the rationale for this anomaly. Administrators are advised to check field YEAR for addition anomalies before adding records, and to periodically check or recalculate YEAR for the entire dataset. Application level controls can be used to reduce the number of addition anomalies.

Recommended Attributes (continued) 9. Additional area information (continued) 9.3 Field name COMMENTS Alias COMMENTS

Field parameters Memo (Dynamic length text) or Text (string), 150 characters Definition This field contains information about an observation or site relevant only to the data collector or their organisation.

Comments should be restricted to information used in the short term such as aiding data entry, or reminding the observer to enter a file note or follow up with a landholder.

Set values No set values Notes Comments are an unreliable way to store information in the medium or long term as they are difficult or impossible to search or

aggregate, and may become detached from the record in data entry or processing. Attribute fields, file notes or other comment management systems should be used in preference. Memo fields are an efficient data structure for storing text, the length expands or contracts to accommodate only the text entered. Some systems, notably ESRI shapefiles, do not support Memo structures and a Text field of length 150 should be used as a substitute.

Optional Attributes 10. Site assessment 10.1 Field name PLOT_LEN Alias PLOT_LENGTH

Field parameters Number (Integer), Short Definition Length of a defined rectangular weed area taken as metres. Notes This field is intended to support the plot based assessment methods used by Parks and Wildlife Commission of the Northern Territory.

If other plot based methodologies are used this should be documented.

10.2 Field name PLOT_WIDTH Alias PLOT_WIDTH

Field parameters Number (Integer), Short Definition Width of a defined rectangular weed area taken as metres. Notes This field is intended to support the plot based assessment methods used by Parks and Wildlife Commission of the Northern Territory.

If other plot based methodologies are used this should be documented.

10.3 Field name STEM_COUNT Alias STEM_COUNT

Field parameters Number (Integer), Short Definition Count of number of stems as described by the methodology defined in the STEM_METHD field. Notes This field is intended to support various stem count methodologies, the methodology must be described in order for the

STEM_COUNT value to be relevant.

10.4 Field name STEM_METHD Alias STEM_METHOD

Field parameters Text (string), 40 characters Definition The stem count methodology that was used generate the value in the field STEM_COUNT. Example Bushfires NT fire plots. Notes Use this field to describe the name of the method used, do not describe the actual details of the method here.

Optional Attributes (continued) 10. Site assessment (continued)

10.5 Field name TREAT_MON Alias TREATMENT_MONITOR

Field parameters Text (string), 40 characters Definition Description of treatment success at a site. Set values 100% Success

> 90 - 99% Success > 50 - 90% Success < 50% Success 0% No impact Not assessable

Notes Records the impact of past treatments applied to the site as a percentage of weed killed by treatment at the date of record ie: today. Be mindful of the impact of past treatments when assessing the present density of the weed in the field DENS_CAT.

Database design Field PAST_TREAT when used with optional attributes TREAT_MON causes the table to fail 3rd normal formal form due to transitive dependency ie: ‘attribute is dependent on the key and only on the key’. The impact of the associated anomalies is considered minor in the context of the weeds database as records are not typically deleted or modified in regular usage. Administrators are advised to check field TREAT_MON for addition anomalies before adding records, and to periodically check or recalculate TREAT_MON for the entire dataset. Application level controls can be used to reduce the number of addition anomalies.

10.6 Field name SITE_COND Alias SITE_CONDITION

Field parameters Text (string), 40 characters Definition How healthy are the plants at the site. Set values Refer to vegetation assessment manuals for site condition indicators. Notes Assess vegetation health without regard to weediness ie: A weedy site is not necessarily unhealthy.

Optional Attributes (continued) 10. Site assessment (continued) 10.7 Field name SOIL_DIST Alias SOIL_DISTURBANCE

Field parameters Text (string), 40 characters Definition Is there evidence of soil disturbance at this site? eg. from cattle, feral animals, machinery. Set values Yes

No Unknown Not recorded Free comment.

Notes No agreed standard exists for soil disturbance. Organisations recording soil disturbance should document the protocol used to determine if soil disturbance has occurred.

10.8 Field name VEG_DIST Alias VEG_DISTURBANCE

Field parameters Text (string), 40 characters Definition Is there evidence of vegetation disturbance at this site? eg. from fire, flood damage, machinery Set values Yes

No Unknown Not recorded Free comment.

Notes No agreed standard exists for vegetation disturbance. Organisations recording vegetation disturbance should document the protocol used to determine if soil disturbance has occurred.

Optional Attributes (continued) 11. Operational factors Database Design

All fields in this section including SURFACTANT, CHEM_TRADE, CHEM_CONC, and ADJUVANTS when used with the attribute TREATMENT causes the table to fail 3rd normal formal form due to transitive dependency ie: ‘attribute is dependent on the key and only on the key’. The impact of the associated anomalies is considered minor in the context of the weeds database as records are not typically deleted or modified in regular usage.

Administrators are advised to check field these fields against the value for TREATMENT for addition anomalies before adding records, and to periodically check these field values against TREATMENT for the entire dataset. Application level controls can be used to reduce the number of addition anomalies.

11.1 Field name SURFACTANT Alias SURFACTANT

Field parameters Text (string), 40 characters Definition Was a surfactant used with application? Set Values Yes

12.2 Field name EQUIPMENT Alias EQUIPMENT

Field parameters Text (string), 40 characters Definition Treatment or survey equipment directly used in weed management operation. Example QuikSpray ®, 50L quad spray, Itracker Database design This field when used with the attribute TREATMENT causes the table to fail 3rd normal formal form due to transitive dependency ie:

‘attribute is dependent on the key and only on the key’. The impact of the associated anomalies is considered minor in the context of the weeds database as records are not typically deleted or modified in regular usage. Administrators are advised to check field this field against the value for TREATMENT for addition anomalies before adding records, and to periodically check the field values against TREATMENT for the entire dataset. Application level controls can be used to reduce the number of addition anomalies.

Optional Attributes (continued) 12. Logistics (continued) 12.4 Field name PLAN_AREA Alias PLAN_AREA

Field parameters Text (string), 40 characters Definition Name for an operational area as defined in a weed management plan or project plan; provides a means of associating weed records

with management areas that are in turn linked to resource allocation or program outcomes. This field is not mandatory as location information can be retrieved from other data layers using a GIS.

Example Manton West, Kakadu, Darwin River TCA Notes The entry value could be defined or derived from the name of the property, a road name, an NT Park name, or by using the parcel

number (laiskey) from the cadastre. A ‘plan area’ should be able to be assigned to a polygon shape that defines its boundary.

12.5 Field name ZONE_NAME Alias ZONE_NAME

Field parameters Text (string), 60 characters Definition A delineated work areas defined as a subset of a zone described above in the field PLAN_AREA. It is intended to assist in reporting

activity against programs. Example Road side surveys Stuart Highway

Property name Manbulloo Paddock name Horse Paddock Park Nitmiluk National Park Laiskey 000 1604

Notes The entry value could be defined or derived from the name of the property, a road name, an NT Park name, or by using the parcel number (laiskey) from the cadastre. A ‘zone’ should be able to be assigned to a polygon shape that defines its boundary. ZONE_NAME can be used to link to a table of zone attributes containing summary statistics.

Optional Attributes (continued) 13. Biocontrol operations Database Design

Fields associated with biocontrol records can be used for single agent of interest relevant to the target species (AGENT/AGENT_CNT) or to record the generalised presence of a biocontrol impact (AGENT_PRES). Studies involving multiple agents would require a separate table (or tables) to weed records. They may be linked to weed records using the ID attribute.

13.1 Field name AGENT Alias BIO_AGENT

Field parameters Text (string), 40 characters Definition Common name of biocontrol agent observed at weed point. Example Carmenta, UU Notes refer biocontrol identification guide for correct common named.

13.2 Field name BIO_ACTIVY Alias BIO_ACTIVITY

Field parameters Text (string), 20 characters Definition Biocontrol activity occurring at weed point. Set values Release

Monitoring Redistribute

13.3 Field name AGENT_PRES Alias BIO_AGENT_PRES

Field parameters Text (string), 12 characters Definition Was the biocontrol agent observed at weed point. Set values Yes


Notes Refer biocontrol identification guide.

Optional Attributes (continued) 14. Summary records (Zone attributes) Database Design

Fields associated with zone records must be stored in a separate table (or tables) to weed records. They may be linked to weed records using the ZONE_NAME attribute. It should be noted that several design challenges exist when integrating zone records with individual weed point records. The characteristics of the GIS or database software used to host the weed records will limit options to link records. Zone attributes extend beyond the scope of this manual and are suggestions only.

14.1 Field name ZN_NAME Alias ZONE_NAME

Field parameters Text,40 Definition Defined work zone name, can link to weed records with ZONE_NAME. Example ‘Four gate road

14.2 Field name ZN_TREAT Alias ZONE_TREAT

Field parameters Text (string), 100 characters Definition A management treatment applied across approach a weed management area. Example ‘Foliar, Glyphosate’

Northern Territory Weed Species List Common names are often used during the weed data collection process. Please use the same exact spelling and ‘leading capital’ format used in this list, as many data processing tools are case sensitive. For example - write Athel pine, not Athel Pine. Alert species, significant threat to the NT: Alert species are likely to cause significant harm if they should enter and become established the NT. Some alert species have been previously found in the NT and managed for eradication, or are established in regions close to the NT. Not all alert species are declared, those which are declared are also listed under the relevant declaration class. Authorities should be contacted urgently if alert species are found or suspected. Declared weeds - schedule of classes

A To be eradicated B Growth and spread to be controlled C Not to be introduced to the Territory All Class A and Class B weeds are also Class C weeds. For more information about these species, refer to the NT Declared List, www.nt.gov.au/weeds Weeds of National Significance (WoNS): WoNS weeds have been identified as a national priority, information and resources are often available to assist in identification and management of WoNS species. Name Convention Notes Punctuation: Punctuation has been removed from species and common names, with the exception of the ‘dash’ character usage described below. This is because many punctuation characters cause problems for spatial or database processing.

Dominant common names: Where a one member of a genus is overwhelmingly represented as a weed the common name for that species may refer to the genus only.

Examples: Hyptis Hyptis suaveolens Mimosa Mimosa pigra

Rubber vine Cryptostegia grandiflora Salvinia Salvinia molesta Stylo Stylosanthes guianensis Common name groupings: Where a genus has a common name eg: Cylindropuntia, the common name for the group is written first followed by the common name specific to the species, or the species name itself if such a common name doesn’t exist. For example, Cylindropuntia imbricata would be rope cactus – devils rope, and Cylindropuntia rosea would be Rope cactus – rosea. Grouping common names enables them to be found easily on a list. Example: Rope cactus - fulgida Cylindropuntia fulgida

Rope cactus - devils rope Cylindropuntia imbricata Rope cactus - rosea Cylindropuntia rosea Rope cactus sp Cylindropuntia sp

Use of sp and spp: The botanical abbreviation ‘sp’ is used when the plant is identified by genus only and the species remains unknown. For weed data collection purposes ‘sp’ represents only those species of primary weed concern where those species may be difficult to distinguish. For example, Cenchrus sp refers only to annual or perennial mission grass, rather than any other Cenchrus species. The use of ‘sp’ is restricted to weed species which are likely be confused. The abbreviation ‘spp’ represents a collective group of species from the same genus and is only used for weeds declared as a species collective, for example Salix spp. Example: Mission grass sp refers to Mission grass – perennial OR Mission

grass - annual (either not both) Subspecies: Subspecies are not listed unless the subspecies forms part of a weed declaration class, they are listed by the abbreviation ‘ssp’. Weeds should not be recorded as sp, spp or ssp unless it is listed as such in the following weed list.
