List of Priority Species and Vegetation LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION Accounts for all BLM required species and vegetation Captures major vegetation types of the planning area Accounts for species that require special attention Is not comprehensive, but representative
5
Matrix forest 3rd order river system Emergent wetland Selecting Focal Targets Select Priority Species and Vegetation (keep number manageable) Start with Ecological Systems (which often include “nested” species) Then Screen for Species that have Special Requirements LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION
6
Group vegetation and species that are related by ecological processes and that co-occur into systems or species assemblages. Examples: –Pine Forest Matrix (4 communities/13 species) –Barrier Island Complex (5 communities/20 species) –Rare Mainstem/Tributary Fish Assemblage (11 species) Selecting Focal Conservation Targets LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION

Lumping or Splitting? “Lump” if they meet all of the following tests: Co-occur on the landscape Require similar ecological processes Have similar health scores, or one can serve as an indicator for the other Have similar effects Examples –Grasslands & grassland nesting birds –Matrix forest & embedded plant community Therefore may ultimately require similar strategic actions Selecting Targets LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION

11
What is our best estimate of how priority species and vegetation are doing? LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION
12
Health Health of a priority species or vegetation is the measure to which the species or vegetation is……. Resistant to change in its structure and composition in the face of external effects and Resilient – able to recover upon experiencing occasional severe disturbance * Natural Range of Variation* LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION
13
To clearly define priority species and vegetation Science-based foundation for establishing current status of a priority species or vegetation and setting desired future condition (goals) Helps to identify effects on the health of each priority species and vegetation and understand with more precision how these disrupt the priority species or vegetation Assists in developing good objectives and focused strategies Guides the design of monitoring protocol and measures of success Helps identify critical knowledge gaps about the system LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION Why assess Health?
14
Aspects of the priority species or vegetation that clearly define or characterize the species or vegetation and determine its distribution and variation over space and time. Characteristics of the species or vegetation, that if eliminated or significantly altered, would result in the demise of the species or vegetation or would shift it into something quite different. Parrish et al. Bioscience 2003 LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION Key Ecological Attributes

Size Species abundance…or Minimum dynamic area Size Species abundance…or Minimum dynamic area Condition Composition (e.g. native vs. nonnative) Structure (e.g. age class distribution) Biotic Interactions (e.g. reproduction) Condition Composition (e.g. native vs. nonnative) Structure (e.g. age class distribution) Biotic Interactions (e.g. reproduction) Landscape Context Environmental regimes/processes (e.g. fire) Connectivity (e.g., access to habitats/resources; ability to disperse, migrate, re-colonize) Landscape Context Environmental regimes/processes (e.g. fire) Connectivity (e.g., access to habitats/resources; ability to disperse, migrate, re-colonize) Key Ecological Attributes LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION
16
Selecting Key Ecological Attributes Pick factors that are critical for long-term persistence o What factors, if degraded, would seriously jeopardize ability to persist for 100+ years? Look for attributes that may be seriously degraded by future human-caused activities Look for a small number of really key ecological attributes (e.g. 3 to 5) o …versus many desirable or descriptive characteristics Key attributes may be refined over time Attributes are what’s important; indicators are what you will measure Pick factors that are critical for long-term persistence o What factors, if degraded, would seriously jeopardize ability to persist for 100+ years?

18
Indicators Measurable entities used to assess the status and trends of a priority species or vegetation’s Key Ecological Attribute(s). Indicators should be: biologically relevant (reflect species or vegetation health) socially relevant (recognized by stakeholders) sensitive to anthropogenic stress (reflect threats) anticipatory (early warning) measurable cost-effective (max. information/unit effort) LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION

20
Very Good: Ecologically desirable status; Requires little intervention for maintenance Poor: Restoration increasingly difficult; May result in extirpation Fair: outside acceptable range of variation; Requires human intervention Good: Indicator w/in acceptable range of variation; Some intervention required for maintenance LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION
21
Natural Range of Variation When these variations are predominantly influenced by non-human factors (e.g., climate, biotic interactions) the variations can be said to be “natural,”or at least “acceptable.” The aim is to manage a priority species or vegetation’s attributes within their acceptable range of variation. Native species & vegetation evolved over long periods with natural variation within their environments. Virtually all key attributes vary over time.

22
Accept uncertainty! General Guidance: View main purpose as capturing the current state of knowledge Don’t worry about information gaps Don’t focus on filling out all boxes! Can return during later planning stages to add more detail (if necessary) LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION

25
General guidance Good/fair threshold is most critical – good usually defines ecological desired condition Don’t get stuck on getting the “right” indicators or values. Fill out, document, and send out for review Prioritize filling gaps for key attributes based on: –Level of concern (poor status), or –Link to actions (what BLM will or could do) LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION
26
Health Assessment - Summary An iterative process with “successive approximations” Begin with a “credible first iteration” Identify 3 - 5 really key ecological attributes for each priority species or vegetation type Determine what you’ll measure for each attribute -- indicators Complete indicator ratings Focus on the difference between Good & Fair thresholds Unless you have a Poor rating for an indicator (then focus on Fair/Poor) Rate the “Current Status” for each attribute Present your initial findings to colleagues/experts for review Continue to improve over time… Identify attributes, indicators & ratings where your uncertainties are most vulnerable LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION
