The Planning Process

Objectives:

1. Provide the rationale for PCRA in the context of good governance in CRM

2. Familiarize participants with some participatory methods and apply these in actual coastal habitat, fisheries and socio-economic assessment

3. Compile a preliminary coastal environment and socio-economic and cultural profile based on PCRA results

4. Analyze results to identify issues and recommend possible management guidelines.

Importance of PCRA:

• facilitates validation of the status of coastal habitats and resources, their current uses and resource users by local community members•generates quantitative technical descriptions of coastal habitats and resources (e.g. fisheries)•documents local and indigenous knowledge crucial for CRM•generates baseline information for the formulation of management strategies•generates baseline information for monitoring and evaluation (i.e. revision and refinement of management actions)

Why is it important to be participatory?

•Facilitates broader understanding of coastal resources uses and users so that communities can make informed decisions about how to best manage local coastal resources•Provides an opportunity to develop and enhance the knowledge of local communities•Contributes to community empowerment •Enhances ownership in decision-making•Facilitates consensus building and information dissemination

• coral reefs, seagrass beds and mangroves are major life-support systems

- source of products and diverse fishery resources- serve as nursery and feeding grounds- provide areas for recreation and tourism- prevent soil erosion and stabilize coastal areas- buffer wave action and protect coastlines

COASTAL AND MARINE ECOSYSTEMCOASTAL AND MARINE ECOSYSTEMEcosystem

Is the basic functional unit of ecology in which both the biotic communities (living) and the abiotic (non-living) environment are inseparably connected and interact, maintaining the equilibrium necessary for

life

Coastal Zone/Area• a band of dry land and adjacent ocean space within a landward limit of 1km from the shoreline at high tide and within a seaward limit of 200m isobath.•Includes adjacent upland and watershed areas that affect and influence coastal ecosystems.•Contains a number of ecosystems with biophysical properties and processes. •

Important Marine/Coastal Ecosystem

Mangrove Forests

Seagrass BedsCoral reefs

Estuaries

Coral reefsCoral reefs

What are Coral Reefs•“rain forest of the sea”•One of the most complex and diverse ecosystems in the world•Primarily consist of hard corals•Slow growing colonies of animals with growth rate ranging between 0.1cm and 10 cm per year in length•Occur along shallow, tropical coastlines•Consist of large and rigid structural mass of calcium carbonate (limestone) formed by cemented skeletal remains resulting from the successive growth and development of reef-building corals•Up to 3,000 species of marine animals may co-exist in a single reef•Can grow to tens of meters high and as long as 2,000 km•18,000 km2 of coral reef areas in the Phils.•1 km2 coral reef = 20 tons of fishes per year

Corals•Colonies of small animals•Each living unit contains algal populations (zooxanthellae) within it own tissue (capable for photosynthesis), providing an energy source for both the coral and the algae•Growth rates ranging between 0.1cm and 10cm per year in length

Figure 1.

Coral reefs contribute about 30% of the fish catch in the country. The Philippines has an estimated 27,000 km2 of coral reefs which occupy 7% our of 30% of coral reefs in Asia.

Ecological Limits required for reef survival: >temperature (18-300C) >salinity (30-36ppt) >Sedimentation must be low so that the water is clear sufficient circulation of nutrient-limited and pollution-free water

Coral reefs are grouped into one of three categories: (a) fringing reefs, (b) barrier reefs, and (c) atoll.

Benefits derived from coral reefs•Home to various species of corals, benthic algae, fish molluscs and crustaceans•Protect the coasts from storms and waves•Popular areas for ecotourism and recreation•Source of medicine

Threats to coral reefs•Siltation and sedimentation•Raw domestic wastes•Industrial and agricultural pollution•Construction near reef areas •Uncontrolled tourism activities •Natural causes•Destructive fishing practices

Dead coral covered with silt

How well are the coral reefs in your area?To be able to know the status of your reef in your area. The

community shall conduct a monitoring scheme to be able to identify the changes done over a period of time. Thus, promote suggestive action for reef restoration and preservation.

How to monitor?There are a lot of ways in monitoring the reef in which all throughout has been

used by scientist. However, to name a few wherein even a local fisherfolk can participate and can easily understand:

• Manta Tow Survey• Point Intercept Transect• Coral Reef Fish Visual Census

Coral Reef Assessment

Manta TowDefinition A manta tow survey is the observation of an underwater area of good

visibility by a snorkeler who is being pulled by a small boat.Purpose Manta tows are used to get a general idea of the various types and

amounts of habitat types and large obvious things in an area. The information incurred from the survey may be used: To help in the selection of sites and number of samples for closer

observation For comparison wit h local perception of the coastal area In the detection of large scale changes (e.g. due to storms and

mass siltation

Requirements•Mask and snorkel (antipara)•Small boat and fuel•Manta board•Pencil attached to slate•GPS or Compass•Map of the area

Methods1. Copy a map of the area onto a slate 2. On the map, plan and mark the tow survey path 3. Choose the items (e.g. live hard coral, dead coral, soft coral, sand/silt

etc.) to estimate. 4. Attach the manta board to the boat using the rope or if no available

board, the observer may cling unto the boat.5. When the observer (snorkeler) is ready and gives the “ok” signal, tow

the observer parallel and over the reef edge along the area to be surveyed.

6. During each tow, the observer estimates the approximate % cover of the items chosen in step 3. The area viewed is up to 10m wide depending on depth and water clarity.

7. After 2 minutes of towing (around 100 to 150m), the timer should inform the driver and the observer to pause and take notes.

8. The observer then records onto the board the tow number and his/her observations of the last 2-minute tow.

9. Repeat step 5-8 until the entire planned tow path has been surveyed.

10. Copy the data onto the data Form and enclose a copy of the map.

DefinitionSnorkel survey is a method used by a snorkler for estimating the relative abundance of living and non-living things on the reef bottom observed within a defined area.

PurposeThe snorkler survey estimates the abundabce of hard corals, dead corals, algae, and various reef substrates which may reflect the health of the reef.

Requirements• Mask & snorkel (antipara)• 50-m transect line• Underwater slates• Pencil attached to the slates• Fins and life jacket (optional)• Picture book of plants or animal types to be quantified• boat

Snorkel Survey

Methods1. Select representative sampling stations to be

surveyed/monitored based on the manta tow results.

2. Copy the data Form 4A (with the selected benthic lifeform types) onto the plastic slates used for writing underwater)

3. Lay the transect line on a constant depth contour. Record the depth

4. Starting at one of the transect line, the snorkeler swims over the transect estimating the % cover of each benthic life form w/in 2.5 m on either side of the transect until the 5-m mark. The estimates of each 5 x 5 m quadrat should total 100%

5. Similarly record each 5-m interval until the entire 50-m transect line has been observed.

6. Add the 10 readings and divide by 10

Fish Visual CensusDefinitionFish visual census is the identification and counting of fishes observed within a defined area.PurposeFish visual census can be used to estimate the variety, numbers, and even sizes of common, easily-seen, easily-identified fishes in areas of good visibility.Requirements•Mask and snorkel (Antipara)•1 or 2 (50-m) transect lines•Underwater slates•Pencil (attached to the slate)•fins (optional)•Picture book of animals (e.g. reef fishes) to be counted•Boat (optional)

Methods

1. Select representative sampling stations and fish types to be census 2. Copy the data Form (for FVC) onto the slates and draw columns for different

size classes. 3. Lay the transect line on a constant depth contour. Record the depth 4. Wait 10-15 minutes for the disturbed fishes to return. Be careful not to

disturb the fishes during the census. 5. Starting at one end of the line, each observer floats on each side of the

transect line while observing 5m to his/her side of the transect and forward until the next 5m mark.

6. Both observers swim to and stop every 5m along the line to record the counts of fish per size class until the transect is completed.

7. Total counts on both sides and transcribe onto Data Form (for FVC).

8. Standardize the subtotal by sample size: Divide the total counts by the number of transect actually observed

Example: (Parrotfish)12+8+9+20+6 = 11 fishes/transect 5 transects

Seagrass Assessment

Requirements• Mask and snorkel (/Antipara)• 100-m rope (approx. 10mm diameter marked at every 10-m)• Pencil (attached to the slate)• Underwater slates• Geographic Positioning System receiver (GPS) or compass• Map of the area• Quadrat (1m x 1m)Methods1. Select representative sampling stations to be surveyed/monitored2. Record the position of each transect. The start (shore end) of the transect is

the most useful reference3. Survey at least 3 replicate transect at each site. Swim the transect along perpendicular to the shore. The length of the transect depends on the size of the seagrass meadows, and should extend to

outer limits of the bed (where seagrass disappears). 4. Place the quadrat to every interval of 10m along the transect.

5. Estimate the % cover of the plants (per species) found in each quadrat and tally it

on the slate board. The sum of the% per species should have an equivalent of 100% in every quadrat.6. Transfer data to the Form and calculate the mean percentage cover in each species.

Example:

Species Q1 Q2 Q3 Mean H. ovalis 15% 20% 10% 15% H. minor 40% 50% 30% 40% Sand 45% 30% 60% 55% Total 100% 100% 100% 100%

Seagrass AssessmentDefinitionSeagrass assessment is the identification and estimation of seagrass species covering within a defined area.

PurposeSeagrass assessment is used to more precisely estimate the abundance of seagrass species which may reflect the health of the reef.

What is a Seagrass?A seagrass is a flowering plant, complete with leaves, a rhizome and a root system. They are found in marine or estuarine waters. Most seagrass species are located in soft (silty or sandy) sediments. Seagrasses worldwide encompass only about 58 species (Kuo and McComb, 1989).

Benefits derived from seagrass beds:> Helps reduce wave and current energy> Help to filter suspended sediments from the water;> Stabilize bottom sediments> Breeding area for selected fish species

> Used as processing feritilizers Seaweeds

> Consumed as food Seaweeds

Threats to seagrass beds:> Siltation and sedimentation> Overharvesting> Pollution
