Sierra Pacific Industries plans new THP near North Fork Stanislaus River



THP 4-12-031 TUO (Flat Tail THP) Sierra Pacific Industries, 689 acres; 90% clearcut, 7% selection, 3% commercial thinning, 1% roadside logging.  Little Rattlesnake Creek, Upper Beaver Creek, Upper Griswold Creek, Lower Beaver Creek, Mill Creek (MD: T5N R16E Sec 1,2,3,9,10,11,12,15,16; T5N R17E Sec 5,6; T6N R16E Sec 36; T6N R17E Sec 31,32). Winter operations, moderate erosion hazard, steep slopes up to 65%, 52 road drainage work sites, oversized units, 10 CA spotted owls within 1.3mi, goshawk nest within .25mi, trees up to 120 years old.  Estimated public comment deadline: 02/10/13.

This THP is about 9 miles NE of Arnold, CA near the North Fork of the Stanislaus River at an elevation of 4,700 - 6,500 feet.  This THP is mostly a clearcut THP listed as 584 acres of Alternative Prescription (clearcut with a seed tree component that leaves no large seed trees behind and requires hand planting).  SPI is planning 276 acres of so called “buffer areas” around units for logging support activities, however they can also log trees if they damage them.  They also want to use ground based equipment on slopes up to 65% in units designed for cable logging (Units 2682, 5029 and 5009c), and to use excavators on slopes between 40% and 50% for fuels treatment.  There are 7 oversized units and 7780 feet of new road construction planned.  SPI is also planning to use a landing in a class II watercourse, and some spur roads to access waterholes in streamside areas.  There are 52 road drainage work sites including culvert cleaning/repair, dip construction/rocking, ditch construction/cleaning and waterhole construction.  1 historic goshawk nest (2002) was reported within .25 mi of Unit 2682 in Section 14.  Botanical surveys have not been done yet - possible habitat for Threebract Onion, Yosemite Onion, Small’s Southern Clarkia, and Slender Stemmed Monkeyflower.  More information is available on the THP Tracking Center website.
