Why is habitat management needed?

Human infrastructure and wildlife

Human infrastructure and development have substantially restricted certain natural disturbance processes that historically provided diverse open habitats for wildlife. In particular, flooding and fire are greatly constrained across the landscape today. While control of flooding and fire is essential to protect human life and property, it also creates an obligation on our part to provide the dynamic habitats for wildlife that these natural processes formerly did.

History of the Massachusetts landscape

Open habitats (grasslands, shrublands and young forest) were part of the New England landscape for centuries prior to European colonization due to:

1. ubiquitous beaver activity
2. spring flooding and ice scouring along rivers and major streams
3. wildfires and fires set by Native Americans in coastal areas and major river valleys
4. occasional catastrophic windstorms

These open habitats started to decline after European colonization due to:

1. extirpation of beaver from Massachusetts
2. extensive development of roads and buildings in portions of the landscape that formerly supported abundant beaver activity
3. flood control
4. fire suppression (especially in portions of the landscape that supported fire-associated natural communities like pitch pine/scrub oak).

Human activity has also reduced the impact of wind storms across the landscape. Today’s forests are relatively young (75-90 year-old) compared to the old growth that once existed, which means that trees are more pliant and resistant to wind disturbance than original old growth forests. Forests are also fragmented by development in many portions of the landscape, which means that when wind disturbance does occur on forested lands, it is typically interrupted by adjacent development.

MassWildlife uses active management to provide a range of grassland, shrubland, and young forest habitats that are no longer created frequently enough by natural processes. Forestry practices, along with mowing, prescribed burning, and invasive plant control are often used to manage sites.
