Section 1536.77  Invasive and Exotic Species Control

 

The purpose of controlling invasive and exotic species is to eradicate or control the establishment and spread of exotic and invasive plants that threaten forest regeneration, productivity, native plant diversity and wildlife habitat.  These practices are priority practices for cost-share funding.

 

a)         Cost-share is authorized for the control of species that are considered a biological threat to the successful establishment or management of the forest flora.  Target species must be identified in the Plan.

 

b)         Invasive and Exotic Species Control.  The flat rate payment for this practice is a variable amount ranging from $90 to $555 per acre.  The base cost is a variable amount ranging from $120 to $740 per acre.  Treatment is to be applied to/attempted for all target species present and result in a minimum mortality or effective control rate of 85%.

 

1)         Cost-share categories and flat rate payments are:

 

 

Category

Flat Rate/A.

Base Cost/A.

 

 

 

A)

Less than 10% of treatment area occupied by target species; brush mowing may be used

$90

$120

B)

10% to 25% of treatment area occupied by target species

$180

$240

C)

26% to 50% of treatment area occupied by target species

$240

$320

D)

51% to 75% of treatment area occupied by target species

$375

$500

E)

More than 75% of treatment area occupied by target species

$555

$740

 

2)         Treatment methods can be combined and may be accomplished mechanically and/or by herbicide application, cutting, pulling, burning or other means.  Cost-share may be authorized for second and third treatments to the same treatment area within a 10-year period, as outlined in the Plan.

 

A)        Additional treatment of Category D or E areas may be cost-shared no higher than Category B.

 

B)        Additional treatment of Category B or C areas may be cost-shared no higher than Category A.
