A fertilizer screening trial in severely repressed lodgepole pine has been established in the vicinity of Anahim Lake BC. This report describes procedures used to establish the trial up to and including pre-treatment measurements, but predates actual fertilizer application. Craig Farnden

A fertilization trial was established in previously repressed pine in Anahim Lake in 2002. Re-measurement in 2003 found an increased foliar response. The 2004 re-measurement established that increased foliar, diameter and height responses occurred.

Growth and Yield and Inventory needs on the Anahim block are many. For reasons discussed above the Chilcotin Plateau has not been well represented by PSP's and other growth and yield type data plots. Additionally, the inventory accuracy at a polygon level is questionable and requires assessment. RJ Vassov & Associates.

Yun Ka Whu'ten Holding Ltd has developed a strategic plan for wildlife in the Anahim Supply Block to provide habitat for naturally occurring wildlife across their historic range. This work is part of a process that began with the Cariboo Chilcotin Land Use Plan. The CCLUP is a higher level plan that guided the application of the Forest Practices Code and provided resource management targets for the Cariboo Region. Together with the CCLUP Integration Report (1998) these documents serve to guide planning at the sub-regional level. The Anahim Round Table sub-regional plan was conducted using a community approach to set resource planning targets. This strategic wildlife plan provides mechanisms to meet targets of the CCLUP and ART documents, provide information to statutory decision makers and landscape level planning, as well as guidance to planners at the operational level. The information used in this plan has been gathered from local studies conducted by YKW, government publications, and information gathered elsewhere. It has been conducted to ensure that most recent information available was used in formulating a wildlife plan. This is especially significant given the large changes in seral distribution and potential impacts to biodiversity expected due to the current MPB epidemic. YKW has made important contributions to research on wildlife populations in this area and an adaptive framework should be used to assess and modify the practices that are implemented where necessary. Finally, forest health planning is also required to decrease the potential for future large scale insect infestations. That planning must include adaptive management regarding the response of wildlife species as well as the development of models capable of predicting the spatial and temporal dynamics of MPB outbreaks in relation to forest management.

We used hair snagging to obtain nineteen samples from 24 traps that were set out over 4 sessions. This yielded a total of 96 capture stations. The majority of samples are from marten (10), but two fisher, two flying squirrel, one short-tailed weasel, one red fox, and one unknown rodent were also among the samples. The remaining samples failed to obtain a result. Initially, capture success was limited with only 2 and 3 samples in the first two sessions, but increased to 5 and 9 samples during the last two sessions. This resulted in an overall trapping success of 20% Larry Davis.

Two remnant Yookwa distribution channels were re-opened in 2003 - the ?900 RB distribution channel? (900m from the mouth of stream on the right bank), and the ?600 RB distribution channel (600m from the mouth of stream on the right bank).
Opening of these remnant channels in 2003 was directed towards re-establishing the multi-channel characteristics of a typical ?high energy? system on an alluvial fan.
Flood flows in November 2007 resulted in damage to the rock-armoured inlet of the ?900 channel? and the formation of a large LWD jam in the main (center) channel resulting in almost all flows being diverted down this channel.
The inlet of the ?600 channel? was reconstructed in 2005. However, the inlet was raised during that work and the 600 channel had not performed as intended since that time. A high, eroding (left) bank at 0+1000m was prescribed for bank protection works in 2005 but these works were not completed at that time; bank protection work took place during August, 2008 in this project.

The Nimpkish River Watershed supports five Pacific salmon species including Coho(Oncorhynchus kisutch), Chinook (O. tshawytcha), Sockeye (O. nerka), Pink (O. gorbuscha) and Chum (O. keta). Also, significant populations of other sport fish including Cutthroat Trout (O. clarki), Rainbow Trout/Steelhead (O. mykiss) and Dolly Varden (Salvelinus malma) also exist in the Nimpkish River system (FISS, 2008). Yookwa Creek itself is known to support populations of Coho salmon, Cutthroat Trout, Dolly Varden, as well as Rainbow Trout and Steelhead. Because of this high value multi-species resource, and the impacts from historic logging activity, Yookwa Creek has been targeted for fisheries rehabilitation activities by Western Forest Products with funding from the Forest Investment Account.
Yookwa Creek was identified as a priority for fisheries rehabilitation by the Nimpkish Watershed Salmon Recovery Plan. M.C. Wright & Associates and Integrated Watersheds Ltd. were contracted by Western Forest Products in 2007 to develop a prescription for restoration works within Yookwa Creek. The lower 2 km of Yookwa Creek consists of an unstable alluvial fan, and restoration projects to date have not resolved the ongoing impacts within lower Yookwa Creek. Fish production will continue to decline if nothing is done to mitigate the major issues in lower Yookwa Creek. To address the ongoing impacts to fish and fish habitat, a more aggressive approach to restoration of lower Yookwa Creek will be required. The proposed restoration works will ultimately benefit fish and fish habitat in both Yookwa Creek and the Sebalhall River. The site was assessed from Oct/07 to Jan/08 for fish habitat, channel morphology, disturbances, and restoration opportunities.

Canadian Forest Products (CanFor) in partnership with the Namgis First Nation ('Namgis) and the International Woodworkers of America (IWA) have been restoring watersheds in the Nimpkish Valley since the inception of the Watershed Restoration Program in 1995. Overview planning, prioritization and prescription studies have led to the deactivation of many forest roads and the construction of numerous instream structures in an attempt to offset and rehabilitate damage caused by forest development. One of the remaining restoration issues - the highest priority in the watershed - is how to address the significant channel changes that have occurred on the Yookwa Creek fan, Sebalhall River and Nimpkish River near Nimpkish Island after floodplain logging in the 1960s and 1970s. Several studies have assessed the conditions of these streams and developed conceptual approaches to address the coarse sediment input of Yookwa Creek, in particular, to Sehalball River. A number of stakeholder meetings have been held over the years to address this issue, the most recent in November 2001, but no firm agreement has been reached on the causes and treatment of the coarse sediment input.
Input data, management assumptions, and analysis results for three Anahim Supply Block Sustainable Forest Management (SFM) Scenarios are documented in this Spatial Analysis Report. This report is based on the FIA ? approved ?Interim Standards for Data Package Preparation and Timber Supply Analysis - Defined Forest Area Management Initiative March 2004?. The three SFM Scenarios presented in this report are as follows: Recreation Scenario This scenario theme focuses on the recreation, tourism, heritage and cultural values present in the Anahim Supply Block. Biodiversity Scenario This scenario theme focuses on landscape unit level management of the biodiversity values present in the Anahim Supply Block. Habitat (Wildlife and Pine Mushroom) Scenario This scenario theme focuses on the habitat values present in the Anahim Supply Block for various wildlife species and pine mushrooms. Protection measures for species at risk under the Identified Wildlife Management Strategy (IWMS) are also relevant.
