Rangeland Inventory & Monitoring

Rangeland Management is:

The use and stewardship of rangeland resources to meet goals and desires of humans.

You cannot make good management decisions if you do not know the effect of past management actions.

CURRENT FUTURE

Information for Management Inventory = record of resources at

one point in time: Land area & pasture sizes Roads & trails Water Vegetation types Corrals, building, fences ? ?

Information for Management Maps for management = resources

references geospatially: Vegetation map Range map Watershed map Land ownership

Information for Management Assessment = evaluation

of condition at one point in time: Riparian Proper

Functioning Condition Rangeland Health Ecosystem Integrity

Usually involve protocols based on “qualitative” attributes (rather than “quantitative” measures).

Monitoring The word "monitor" is rooted in a

term meaning "to warn." Enable managers to take

appropriate actions and change course if needed.

Monitoring After a wildfire, a land manager of

this sagebrush steppe area in Southern Idaho may implement a monitoring program to determine if and when the burned area recovers a plant community similar to an unburned area. 

MonitoringA rancher may

implement a monitoring protocol to determine if a new grazing system is affecting establishment of sedges or willows along a stream improving the stability of stream banks. 

MonitoringA leafy spurge

patch such as this could be monitored to determine if the weed management plans are effective. 

Monitoring: The Main Steps Complete inventory – know resources

available

Develop objectives Design and implement management Design the monitoring methodology Evaluate management actions.

Monitoring: The Main Steps What do I need to know to make

good management decisions? What/how can I realistically

monitor?

Set SMART Objectives

SMART Objectives: Specific – Objectives should specifically state

what you want to achieve on the land you are managing.

Measurable – It must be possible to measure whether you are meeting the objectives or not.

Achievable - Are the objectives you set, achievable in your current setting? Consider environmental constraints, societal expectations, economic parameters, legal requirements, and technological limitations.

Realistic – Set objectives that you can realistically achieve given the natural and management context of your situation.

Time – Set a time horizon for management objective.

SMART Objectives:To set SMART objectives must know: What resources you have:

Land Human capital Economic

What you and your land of: Ecological site Climate Condition

What you are capable of: Skills Abilities Knowledge

Examine TrendTrend = upward or downward based on

conditions measured at least 2 points in time: Used to evaluate management actions Measures change over time Best if done frequently

Apparent Trend = attributes measured at one time point in time to infer trend Often misleading

Fifty Years of Change in a Shadscale Stand in IdahoLee A. Sharp, Ken Sanders & Neil Rimbey

The following rangeland photo journal charts the changes that have occurred in a shadscale (Atriplex confertifolia) stand in southern Idaho starting in1951.

Photos of the site have been taken annually since 1955, but the selected photos show the dynamic nature of the site.

Interpretation of data Determine if management

objectives have been achieved if not, why?

Determine if management objectives need redefining are they realistic? have your goals changed?

Determine needed management action

“Pictures are worth a thousand words” But only if you know the true story

of what happened over time. Photos are used by critics, but they

seldom make the correct interpretation.

The permittee is the person most likely to know the true story.
