Nature Mapping Expeditions In The Little Spokane
Watershed
To date twelve nature mapping expeditions have explored sixteen sites at
four locations in the Little Spokane Watershed. Seventy three unique
species were observed and journaled. A total of 566 individual species
were recorded in 181 species journal records. Sixteen generalized habitats
were identified at these sites.
Anyone Can Be A Nature Mapper
Nature mapping expeditions can be done by anyone interested in nature;
individuals, families, and groups including elementary school classes through
university classes. At a specific nature location one or more sites are
quietly observed for five or more minutes. An observation journal is used
to record each species and how many there were.
Making Nature Maps
The Council has assisted with the development of a nature mapping database
and computer program that displays and prints maps for nature mapping expedition
locations and sites. A site or location can be clicked on and all the species
that have been observed at the particular site or location are displayed.
There is also a pull down window that allows the selection of one of the
species and then all the sites and locations with the selected species
are then highlighted. In addition to the maps, charts and graphs can be
made showing species, habitat, and other inter-relationships.
Washington Stateís Nature Mapping
Periodically the journal species records along with information about each
expedition is to be sent to Washington Stateís Nature Mapping Program,
which is a joint outreach program developed by the Washington Department
of Fish and Wildlife and the University of Washington Gap Analysis Project.
This information is then entered into Washington Stateís Gap Analysis database.
Nature Mapping Is World Wide
The purpose of Washington Stateís Nature Mapping Program is to promote
biodiversity studies through citizens and school-based data collection
and research. The objective is to empower citizens to plan for and to manage
the stewardship of the watersheds where they live. More than half of the
states and other regions of the world have Gap Analysis Projects.
How Nature Mapping Is Used For A Better Quality Of Life
ìGap Analysisî is intended to be a proactive approach to identify and
protect geographical areas - habitats - that are critical to individual
species or groups of species before their existence is threatened. ìGap
Analysisî focuses on maintaining available populations of native species
in their natural habitats. The data base information and computer mapping
and computer analysis - Geographic Information Systems (GIS) - is
used to identify biodiversity gaps that are not yet adequately protected
through land ownership or appropriate management.
How Biodiversity Gaps Are Identified
The analysis involves the use of satellite imagery to create initial vegetation
maps of the state. Additional information is mapped in layers that can
be overlaid on each other. These map layers include the distribution of
species; the lakes, rivers and streams; geological features; soil types;
land use and land ownership; roadways and topography. Areas important to
individual species, groups of species, or of high biological diversity
- species richness - can then be identified and the degree of protection
assessed.
