Step 1 : General Development Information

In this step, give the initial conditions about the development site. Estimate the original amount of early successional forest/shrubland and late successional forest across the entire site. For tree canopy cover in built areas, estimate tree canopy cover in proposed areas that will contain a substantial amount of human-modified structures such as rangeland, crops, mowed grass, buildings, and asphalt. Essentially any trees currently found in proposed residential/commercial areas will count towards the original tree canopy cover.

Early successional forest fragments are defined here as 1) shrublands composed primarily of shrubs with some scattering of trees and grassland patches, and 2) very young forests composed of primarily planted pine saplings and/or pioneer species such as black cherry (Prunus sp.), trees that are 0-15 years old, and tree height is typically less than 30 ft. Late successional forest fragments are where most of the trees that form the canopy are over 30 ft tall, including both relatively young forests with trees 15-50 years old and mature forests with trees 50+ years or older. To be considered a forest fragment, the minimum size is 1 acre.


Step 2 : Forest Fragments as Breeding & Wintering Habitats

For this step, only count conserved forest fragments where there are no substantial human-modified structures contain within it (e.g., rangeland, crops, mowed grass, buildings, and asphalt). See detailed explanation.

Step 3 : Forest Fragments as Stopover Habitat

Many forest birds, along their migratory routes, require forest areas to stop, rest, and refuel during the spring and fall. These forest areas are called stopover sites; forest fragments, from as small as 1 acre, can provide important stopover habitat for migrating birds. See detailed explanation.

1)  17 acres or larger*How many acres of conserved forest will be in patches of 17 acres or larger?

(whole #s only)

2)  From 13 to less than 17 acres*How many acres of conserved forest will be in patches sized 13 acres to less than 17 acres ?

3)  From 9 to less than 13 acres*How many acres of conserved forest will be in patches sized 9 acres to less than 13 acres?

4)  From 5 to less than 9 acres*How many acres of conserved forest will be in patches sized 5 to less than 9 acres?

5)  From 1 to less than 5 acres*How many acres of conserved forest will be in patches sized 1 to less than 5 acres?

Step 4 : Tree Canopy Cover within the Built Matrix

Estimate the number of acres of tree canopy cover that remains in the built areas after construction of buildings, roads, and other built structures. Certain species can use these built areas as breeding and wintering habitat and also some migrants will use it as stopover habitat.See detailed explanation.
