00Enrolled HB 420 01 Relating to riparian protection standards for forest resources and practices; and providing for 02 an effective date. 03 _______________ 04 * Section 1. The uncodified law of the State of Alaska is amended by adding a new section 05 to read: 06 FINDINGS AND PURPOSE. (a) The legislature finds that 07 (1) AS 41.17 (Forest Resources and Practices Act) 08 (A) establishes a policy of protecting riparian areas from significant 09 adverse effects on fish habitat and water quality from timber harvest activities; and 10 (B) divides the state into three forested regions for purposes of riparian 11 area protection, in recognition of the fact that standards necessary to adequately 12 protect fish habitat and water quality may vary according to the different 13 characteristics of each of these three regions; 14 (2) AS 41.17 (Forest Resources and Practices Act) has already established
01 detailed riparian protection standards for the southern coast (Region I) and interior (Region 02 III) of the state, which all available evidence continues to indicate adequately protect riparian 03 areas in these regions; however, the legislature has not previously established similarly 04 detailed standards for inland southcentral Alaska (Region II), because of the need for 05 additional research and scientific collaboration specific to that region; 06 (3) an intensive analysis of riparian habitat characteristics in Region II has 07 been completed, and proposed detailed standards for riparian protection in Region II that are 08 based on the unique nature of riparian ecosystems in Region II have been developed; these 09 proposed standards have been endorsed by the Board of Forestry and the Department of 10 Natural Resources; 11 (4) the proposed standards for Region II recognize that certain distinctive 12 features of riparian areas in Region II exist that warrant special protection standards that differ 13 significantly from the standards applicable to either Region I or Region III; these distinctive 14 features include 15 (A) a relative abundance of wide, unconfined, and dynamic river 16 channels in forested areas; the falling of trees into these rivers as a result of the 17 frequent shifting of river banks is a major contributor of beneficial large woody debris 18 to these channels; trees along these rivers can therefore become an important source of 19 large woody debris even though they are currently located relatively far from the river; 20 (B) a greater diversity and wider distribution of fish species, including 21 high value resident fish species, than in other regions of the state; 22 (C) more intensive use of fresh water of Region II for sport fishing 23 than in other regions of the state; and 24 (D) a relatively low volume for each acre of riparian timber and a 25 relatively high proportion of hardwoods that have a shorter residence time as large 26 woody debris; as a result, a wider no-harvest area is necessary along dynamic river 27 channels in Region II to provide a volume of large woody debris equivalent to that 28 yielded by a smaller buffer in other regions; 29 (5) the proposed standards for Region II are responsive to the distinctive 30 features listed in (4) of this subsection. 31 (b) The purpose of this Act is to further the goal of AS 41.17 (Forest Resources and
01 Practices Act) of region-specific riparian protection standards in this state by adopting 02 standards that have been tailored to the unique conditions of the inland southcentral area of 03 the state. 04 * Sec. 2. AS 41.17.116 is repealed and reenacted to read: 05 Sec. 41.17.116. Riparian standards for private land.
