wetland graphic map Wetland Inventory & Map Project

Wetlands play a critical role in our lives. They sequester carbon, produce oxygen and distill water in controlling pollution. Wetlands are an important habitat and provide a variety of food sources for animals including mammals like people. Have you ever enjoyed cranberries, crab cakes, shrimp, or wild rice? They all come from wetlands. Wetlands add aesthetic value to property. Because they are so attractive to wildlife, wetlands can be outstanding recreation sites for those who enjoy watching or harvesting wildlife. Scientists are showing us that wetlands play a critical role in cleaning, recovering and controlling fresh water. They serve as landmarks and historic reminders.

Your community has decided to inventory all their wetlands . (Wetland Mapping and Classification of the Kenai Lowland, Alaska) The goal is to create a map and a database with all the information collected for each unique wetland. This information will be used to make decisions regarding development. You will be participating by collecting data. Functions and Values of Wetlands

Begin by reviewing the many resources at Identifying Wetlands. and Chapter 2: Classification of Wetlands

1. Select an area to inventory. This could be your school's campus, a local public park or a neighborhood.

Respect property rights. Do not enter private property without permission.

2. Make a rough map of the area you will be mapping that includes major structures, streets and major waterways. If there is a locally available map of your community, you could use it. (Sometimes the local Chamber of Commerce, visitors agency or realtors have free local maps.)

3. Review how to classify wetlands

Wetland Definitions and Classifications in the United States

4. Data to consider collecting:

(make a paper form or a spreadsheet/database with the data to be collected so that each wetland is on a separate form or ss row or db record.)

bullet Location - use GPS if possible, use street address if it is not.

bullet Wetland type - see classification info above

bullet Water quality - macroinvertebrates assessment

bullet Water temperature & air temperature

bullet Water chemistry (salinity, pH, color, transparency, nutrients)

bullet Soil - structure and color, pH, temperature

bullet Which type is it - Lacustrine wetlands are associated with lakes. Riverine wetlands are found along shores of rivers and streams. Palustrine wetlands are not associated with lakes, rivers or streams.

bullet Land use around the wetland - agricultural, housing low density/high density, undeveloped, industrial, mill dams

bullet Land tenure - public accessible, public non accessible, private

bullet Biota - note several plant and animal species - scientific name & common name

bullet Make note of Native and Nonnative organisms esp Purple Loosestrife

bullet Digital photo of the wetland - You could have the goal to take one in each season to present a complete picture.

bullet Impact on area. Example - provides habitat for many birds, controls water runoff from road or property, nationally, state or regionally significant site like "on the Atlantic flyway attracts migratory species".

Process:

Divide the site into sub areas with two or 3 people working in each sub area.

Assemble your tools. What will you need?

Collect the data. How will you avoid counting wetlands more than once?

Wetlands Mapper | NatureMapping

Publish your findings.

bullet What is the diversity of the wetlands and their species?

bullet What percentage of the land in your region is wetland?

bullet Identify an area that would benefit from remediation.
