Hudson Valley Habitat Management Decision Tree (for managing bird habitats):
Mixed Landscape

Landscape that is between 50% and 70% forested, with the remainder in open habitat conditions or occupied by human infrastructure.

Step Mixed-1: What is the current condition of the property?

Non-forested (grassland, crop field, old field, etc.); clearable by brush hog: Go to Step Mixed-2
Forested (enough trees present that brush hogging is not possible): Go to Step Mixed-3c

Step Mixed-2: What is the size of the property to be managed?

Step Mixed-3a: What is the condition of the adjacent properties?

>50% “open” land uses (e.g., crops, pasture, hayfields, etc.): Consider managing the property for Shrubland and/or Early-successional Forest birds if the property is <10 acres or for Early-successional Forest and/or Mature Forest birds if the property is >10 acres.
>50% forested, with most of the forest in a relatively mature state: Consider managing the forest for birds that require Mature Forest habitat in combination with some Early-successional Forest habitat (not to exceed 50% the property at any time).
>50% forested, with most of the forest in a relatively young (i.e. early-successional) state: Consider managing for Mature Forest birds.

Step Mixed-3b: What is the condition of the adjacent properties?

>50% “open” land uses (e.g., crops, pasture, hayfields, etc.): Consider managing the property for Grassland birds.
>50% forested, with most of the forest in a relatively mature state: Consider managing for birds that require Mature Forest habitat in combination with some Early-successional Forest habitat (not to exceed 10% of the property at any time).
>50% forested, with most of the forest in a relatively young (i.e. early-successional) state: Consider managing for Mature Forest birds.

Step Mixed-3c: What is the condition of the adjacent properties?

>50% “open” land uses (e.g., crops, pasture, hayfields, etc.): Consider managing the property for Mature Forest birds if the property is <200 acres or, if the property is >200 acres, consider managing for birds that require Mature Forest habitat in combination with some Early-successional Forest habitat (not to exceed 10% of the property at any time).
>50% forested, with most of the forest in a relatively mature state: Consider managing the majority of the property for birds that require Mature Forest habitat with smaller patches within the property managed for Early-successional Forest birds (3-25 acres each, their total not to exceed 25% of the property or in conjunction with other early-successional habitat in the landscape not to exceed10% of the landscape at one time).
>50% forested, with most of the forest in a relatively young (i.e. early-successional) state: Consider managing for Mature Forest birds.
