HABITAT MAPPING EXERCISE
See below for
downloadable
files
Objectives:
- Characterize
habitat in the field.
- Develop
habitat mapping skills and relate them to aerial photographs,
- Appreciate
the usefulness of a well-developed map product.
- Get
outside!
Assignment:
- Examine
the copy of the aerial photo of the Red River Valley Natural History
Area. Determine where you are on the photo.
- Make
a walking reconnaissance of the area. Note topography, vegetation,
composition and age structure of the vegetation. Take notes as you
travel. Mark your location on the air photo and describe in your notes
what you see at each point. Remember, the aerial photo may not be current
(e.g., 10 years old) and you must mentally compensate for years of natural
change (succession) plus some possible anthropogenic (human caused)
changes.
- Draw
lines on the photo delineating major habitat types as characterized y by
the same topography and/ or vegetation. Some vegetation may be the same
species but of different ages in different areas, suggesting a separate
habitat type.
- After
“roughing in” the habitat type map on your photo (showing habitat types,
roads, fences, etc.), make a tracing onto white paper oriented lengthwise
(landscape) so that your legend can be presented to the right or below the
map.
- Include
a separate description of the habitats noting dominant species present,
ages of trees, density of different layers (if a forest), etc.
- Characteristics
of a good habitat map:
- A
good habitat map should be accurate, informational and attractive. Plan
you map so that it has a uniform border of “white space” around the map
and legend.
- Every
place inside the boundary should be part of a labeled habitat or field,
road, etc.
- Use
symbols or colors to designate habitat types that are suggestive of the
habitat. For example, use [insert wavy lines] or the color blue
to indicate water.
- The
following should be on the map:
- title,
legend, scale, natural and existing human-made features (roads,
buildings, fences), direction of north, map developer (your name), date,
reference map used.
- When
you have completed the map, ask yourself the following questions:
Would
it be meaningful to someone else? Does it have a balanced layout? Is it
something I am proud to put my name on?
- Be
sure to hand in your map, your habitat descriptions, and your field map
& notes.
