Objective (s) 11 Indicator(s) Target/Measure <strong>Management</strong> Considerations<br />
2. To maintain a<br />
distribution of<br />
mature, old and<br />
early seral<br />
forest reflective<br />
of the natural<br />
disturbance<br />
regime.<br />
3. To maintain<br />
connectivity of<br />
old and mature<br />
forest cover<br />
within<br />
Landscape<br />
Riparian<br />
Corridors (See<br />
Map 6, page<br />
71).<br />
a. Amount of<br />
mature and old<br />
seral forest<br />
retained by<br />
BEC subzone<br />
(See Map 5,<br />
page 70).<br />
b. Amount of<br />
early seral<br />
forest at any<br />
one time by<br />
BEC subzone<br />
(See Map 5,<br />
page 70).<br />
c. Amount of old<br />
seral forest at<br />
any one time,<br />
by BEC<br />
subzone (see<br />
Map 5, page<br />
70).<br />
a. Amount and<br />
quality of old<br />
and mature<br />
forest cover<br />
within<br />
Landscape<br />
Riparian<br />
Corridors.<br />
% retention of<br />
mature and old seral<br />
forest by BEC<br />
subzone: 13<br />
ESSFwv >61%<br />
ESSFmc >44%<br />
ICHmc >46%<br />
SBSmc >35%<br />
Maximum amount<br />
of early seral forest<br />
(< 40 years) by BEC<br />
subzone: 12<br />
ESSFwv 17%<br />
At least 70%<br />
retention of structure<br />
within Landscape<br />
Riparian Corridors.<br />
No alteration of<br />
fluvial or floodplain<br />
ecosystems 14 that<br />
may be subject to<br />
frequent or<br />
infrequent flooding.<br />
Mature forest is defined as > 120 years<br />
in ESSFwv and ESSFmc; and > 100<br />
years in the ICHmc and SBSmc. Old<br />
forest is defined as >250 years except in<br />
the SBSmc where it is defined as >140<br />
years.<br />
Old forest is defined as >250 years<br />
except in the SBSmc where it is defined<br />
as >140 years.<br />
NOTE: Much of the % retention<br />
required for old seral forest has been<br />
spatially identified in Core Ecosystems,<br />
non-operable forest, Special<br />
<strong>Management</strong> Zones, and the <strong>Babine</strong><br />
River Corridor park.<br />
Operational plans for harvesting within<br />
Landscape Riparian Corridors (see Map<br />
6, page 71) should consider the harvest<br />
pattern adjacent to the corridor. For<br />
example, clearcuts adjacent to the<br />
corridor will constrain harvesting<br />
strategies within the corridor.<br />
Conversely, modified harvesting<br />
adjacent to the corridor will increase the<br />
flexibility for harvesting in a corridor<br />
(see Table 4, page 19).<br />

A fluvial or floodplain ecosystem is one in which the floristic community is influenced by the flooding from an adjacent<br />
stream or river. This includes subsurface, periodic over-bank or annual over-bank flooding.<br />
