Conservation Design –

Describing desired future conditions at landscape scales

Developing tools that facilitate the efficient attainment of those future conditions

Conservation design is one element of an adaptive approach to science-based habitat conservation, that is,

Planning;Implementing;Evaluating planning

assumptions and management

outcomes;Planning anew with better

information

FUNDAMENTAL QUESTIONS

• What is our goal or objective?

• What management tools should we use?

• What resources are available ?

• What criteria will we use to evaluate our strategy?

Step 1. Define Conservation Goals

Option 1 – Establish measurable populationobjectives for priority species* (an explicit population approach)

*From National or State Plans and Initiatives

Option 2 – Describe historic abundance and distribution of habitat once capable of sustaining populations at satisfactory levels (an implicit population approach)

Each approach is founded on a set of assumptions about how populations respond to habitat and landscape conditions.

Population objectives are arbitrary, that is, they are a value-based statement of how many individuals, or discrete populations, of a species we want. However, population objectives must be:

•Linked among spatial scales •Measurable with existing or anticipated surveys•Informative to the question of how much habitat is needed•Performance metrics that are appropriate to the spatial scale (numbers at continental scales versus vital rates at local scales)•Communicable

Option 1- Measurable Population Objectives

Step 1. Define Conservation Goals

By-passing explicit population objectives by starting with a description of an historic landscape configuration presumes that population-habitat relationships and limiting factors are the same today as they were historically

Option 2 – Describe Historic Conditions

Step 2: Develop the tools to effectively and efficiently attain conservation goals

1. Select focal species;

Focal species may represent the habitat needs of a broader array of species, or have high socio-economic or legal stature.

The suite of focal species should represent the relevant range of habitat and landscape types and disturbance/management.

Step 2: Develop the tools to effectively and efficiently attain conservation goals

2. Identify the factors most limiting populations of focal species;

3. Systematically apply good scientific information;

4. Identify the actions and sites that will most efficiently affect the limiting factors (a decision support tool);

1. Select focal species;

What programs do we direct or can we influence?•Unique program goals and priorities•Allowable program practices, e.g., CRP is mainly a grassland restoration program•Funding

What are the programmatic gaps?•Species or other environmental functions•Authorized management practices•Funding

Can partnerships help address these gaps?

Step 3: What resources are available ?

Conservation Design is most valuable when linked with Conservation Delivery and Evaluation in an iterative, adaptive cycle

Step 4: What criteria will we use to evaluate our strategy?

Evaluation - 3 Necessary Inferences:

•Effects of a particular action on habitat and the species’ response•Program and agency accomplishments•Net progress toward population objectives

Monitor a subset of management sites

•Did the action result in the expected habitat response?Enables us to tweak our management tactics

•Did species respond as predicted?Enables us to refine our models

Monitor populations at appropriate scales

•Did we achieve our stated objectives?Enables us to measure performance and adjust our goals and strategies

A credible process for conservation design must:

•be a systematic application of existing biological knowledge;• be explicit about uncertainties and potential errors so as to guide evaluation and research activities;•be transparent and communicable; and•yield information that is useful for managers delivering conservation plans and practical for landowners to apply.

The continuing challenge will be to maximize aggregate benefits to the full range priority species and environmental functions by coordinating partner actions and integrating programs without sacrificing individual program efficiency.

In other words, we’re still learning how to do strategic,partnership-based conservation
