A.
APPLICABILITY. The requirements of Section 7 apply to all timber
harvesting and related activities in shoreland areas within 250 feet,
horizontal distance, of the normal high water line of:
1. Rivers below the 50 square mile drainage
point in the jurisdiction of the Land Use Planning Commission
2. Rivers below the 25 square mile drainage
point in municipalities not subject to the jurisdiction of the Land Use
Planning Commission;
3. Great Ponds
and nonforested freshwater wetlands 10 acres or larger;
4. Any coastal wetland; and,
5. Any size pond or freshwater wetland
identified by the Department of Inland Fisheries and Wildlife as significant
wildlife habitat or essential wildlife habitat.
B.
SHADE AND TREE RETENTION
STANDARDS
Timber harvesting and related activities in shoreland areas
subject to the requirements of Section 7 must leave adequate tree cover and
shall be conducted so that a well-distributed stand of trees is retained. The
requirements of this section may be satisfied by following one of the following
three options:
1.
Option 1 (40%
volume removal), which requires:
a.
Harvesting of no more than 40 percent of the total volume on each acre involved
of trees 4.5 inches DBH or greater in any 10 year period is permitted. For the
purposes of these standards volume may be considered to be equivalent to basal
area;
b. A well-distributed stand
of trees which is windfirm, and other vegetation including existing ground
cover, must be maintained; and,
c.
Within 75 feet, horizontal distance, of the normal high water line of shoreland
areas regulated under this section, there must be no cleared openings. At
distances greater than 75 feet, horizontal distance, of the normal high water
line, timber harvesting and related activities must not create single cleared
openings greater than 14,000 square feet in the forest canopy. Where such
openings exceed 10,000 square feet, they must be at least 100 feet apart. Such
cleared openings will be included in the calculation of total volume removal.
For the purposes of these standards, volume may be considered equivalent to
basal area.
2.
Option 2 (60 square foot basal area retention), which requires:
a. The residual stand must contain an average
basal area of at least 60 square feet per acre of woody vegetation greater than
or equal to 1.0 inch DBH, of which 40 square feet per acre must be greater than
or equal to 4.5 inches DBH;
b. A
well-distributed stand of trees which is windfirm, and other vegetation
including existing ground cover, must be maintained; and,
c. Within 75 feet, horizontal distance, of
the normal high water line of shoreland areas regulated under this section,
there must be no cleared openings. At distances greater than 75 feet,
horizontal distance, of the normal high water line, timber harvesting and
related activities must not create single cleared openings greater than 14,000
square feet in the forest canopy. Where such openings exceed 10,000 square
feet, they must be at least 100 feet apart. Such cleared openings will be
included in the calculation of total volume removal. For the purposes of these
standards, volume may be considered equivalent to basal area.
3.
Option 3 (outcome
based), which requires: An alternative method proposed in an
application, signed by a Licensed Forester or certified wildlife professional,
submitted by the landowner or designated agent to the Bureau and approved by
the Bureau, which provides equal or better protection of the shoreland area
than this rule.
Landowners must designate on the Forest Operations
Notification form required by
12 M.R.S.
§§8881
et seq.
(Supp. 2013) which option they choose to use. If landowners choose
Option 1 or Option 2, compliance with this section will be determined solely on
the criteria for the option chosen. If landowners choose Option 3, timber
harvesting and related activities may not begin until the Bureau has approved
the required application.
The Bureau may verify that adequate tree cover and a
well-distributed stand of trees is retained through a field procedure that uses
sample plots that are located randomly or systematically to provide a fair
representation of the harvest area.
