BIODIVERSITY IN THE MANAGED LANDSCAPE: THEORY AND PRACTICE
CONFERENCE IN SACRAMENTO JULY 13-17, 1992         (PART 5)
From: Evelyn Hamilton <ehamilton@galaxy.gov.bc.ca>

             
            VII. SETTING OBJECTIVES AND PRIORITIES

Interfacing science and conservation
Paul Risser, Univ. New Mexico, Albuquerque, NM

He  focused  on  the need to set objectives. He reviewed the USFS
biodiversity objectives which are:

 1. to determine what species are  sensitive  to  management  ac-
    tivities,

 2. to develop indicators,

 3. to research management methods,

 4. to test tools,

 5. to understand ecosystem functioning,

 6. to evaluate how networks can be used in high use areas.



What do we need to do?

 1. Insure for national coordination.

 2. Expand  the Pacific Northwest Gang of 4 approach: expand this
    process used to identify critical owl habitat  to  additional
    areas.

 3. Establish rapid assessment teams and do gap analysis.

 4. Conduct human settlement experiments.

 5. Include  private  sector and NGOs in our research and manage-
    ment programs.

 6. Conduct social science experiments where we  look  at  social
    science   issues,  relationship  to  decision-making,  system
    transformation and the need for a whole new  social  and  in-
    stitutional structure.

 7. Coordinate  databases  and inventories nationally and look at
    how this information is used in decision-making.


                  VIII. MANAGEMENT STRATEGIES

Strategies for conserving endemic plants
Donald Falk, Center for Plant Conservation, St. Louis, MO

In the US there are about 20K plants, of which 22% are threatened
or endangered, with 4% facing possible extinction  in  10  years.
Climate  change  could  have  severe  impacts on rare species. He
identified the need for population biology research.


Strategies for conserving rare animals
Scott Derrickson, Smithsonian Institute Conservation and Research
Center, Front Royal, VA

In the US there are 520 endangered species, 277 are  animals  and
243  are  plants  and  there  are  161 threatened species, 97 are
animals and 64 are plants. Recovery plans have be drafted for 382
species. Several thousand species await listing.



New perspectives for conserving ecological diversity  in  managed
landscapes
Hal Salwasser, USFS, Washington, D.C.

Forest  ecosystem  management is the new objective. The objective
is to blend the needs of people and the  environment  to  sustain
diverse healthy ecosystems. Their plan involves:
    Regional  Conservation  Strategies  for the recovery of large
    wide ranging species (e.g. Spotted Owl).

 1. Identifying desired  future  conditions  and  using  this  in
    planning.  These  plans  identify protected areas, management
    emphasis zones (e.g. Bridger Teton Nat. Forest),

 2. Restoration at the landscape level through the reintroduction
    of fire (e.g. Shawnee Nat. Forest) and conserving networks of
    communities.


Their ecosystem management guidelines specify that they will:

 1. sustain diversity,

 2. work with nature,

 3. consider scale effects,

 4. focus on desired future conditions and results,

 5. coordinate strategies on common issues,

 6. get people to participate,

 7. integrate information,

 8. adapt to change.


Managing biodiversity on private lands
Michael O'Connell, World Wildlife Fund

The World Wildlife Funds's  objectives  are  to  maintain  viable
populations  and  natural  distributions  of  native  species and
communities in regional landscapes. They do this  by  classifying
sites  in  terms of their significance and establishing different
objectives for each class.


Modelling vertebrate habitats in Pacific Northwest forests  under
global change: Conceptual and methodological issues
A. Hansen, OSU Corvallis, OR

Their  objective  is  to determine which species are sensitive to
landscape change. They characterized landscape pattern in the  W.
Cascades  using  Landsat  TM  data to describe habitat structure.
They used a model called Paysage which involves ZELIG - a  forest
stand development model and GIS Arc Info. ZELIG was used to model
tree  growth  and  establishment  and  mortality, based on light,
temperature and  soil  moisture.  It  was  used  to  follow  snag
dynamics  and  CWD.  They  used the model on a landscape level to
determine stand types for each disturbance regime and topographic
setting.
