    Macrolepidoptera Inventory of the Chilcotin District

    Macrolepidoptera Inventory of the Chilcotin District Aud I. Fischer – Biologist Jon H. Shepard - Research Scientist and Crispin S. Guppy – Research Scientist January 31, 2000 2 Abstract This study was undertaken to learn more of the distribution, status and habitat requirements of B.C. macrolepidoptera (butterflies and the larger moths), the group of insects given the highest priority by the BC Environment Conservation Center. The study was conducted in the Chilcotin District near Williams Lake and Riske Creek in central B.C. The study area contains a wide variety of habitats, including rare habitat types that elsewhere occur only in the Lillooet-Lytton area of the Fraser Canyon and, in some cases, the Southern Interior. Specimens were collected with light traps and by aerial net. A total of 538 species of macrolepidoptera were identified during the two years of the project, which is 96% of the estimated total number of species in the study area. There were 29,689 specimens collected, and 9,988 records of the number of specimens of each species captured on each date at each sample site. A list of the species recorded from the Chilcotin is provided, with a summary of provincial and global distributions. The habitats, at site series level as TEM mapped, are provided for each sample. A subset of the data was provided to the Ministry of Forests (Research Section, Williams Lake) for use in a Flamulated Owl study. A voucher collection of 2,526 moth and butterfly specimens was deposited in the Royal BC Museum. There were 25 species that are rare in BC, with most known only from the Riske Creek area.

In addition, Yakama tribal members provided information and direction that was critical to the preparation of this Forest Management Plan. Achievement of their goals, desires, and visions for the future of the Yakama Forest was the basis for the development of the management directions in this document. The leadership and advice of the Yakama Tribal Council, General Council Officers, the Yakama Agency Forest Manager, and the Yakama Agency Superintendent were significant to the development of the FMP. Particularly noteworthy was the assistance and encouragement provided by the Chairman and members of the Tribal Council Timber, Grazing, Overall Economic Development Committee.

    Spruce Tree Challenge! Take a Walk in the Woods with This Self-Guided Scavenger Hunt to Learn More About White and Black Spruce Trees

    Spruce Tree Challenge! Take a walk in the woods with this self-guided scavenger hunt to learn more about white and black spruce trees. Developed for use in Denali National Park and Preserve, but adaptable to interior Alaska. 1. Meet a spruce tree—make a new friend! Spruce trees are evergreen trees with needles and cones. Take a walk and choose a spruce tree to “meet”; find one with cones on it. Then make and record observa- tions to find out what kind of spruce tree you just met. Please be kind to your new friend; touch it gently and leave all cones and branches on the tree. But, feel free to shake hands with or give your tree a hug when introducing yourself! Find the large cones near the top of your tree. Draw or describe their shape. What kind of spruce is your new friend? Circle one. Picea glauca (white spruce)- long cylindrical cones on branch ends and clustered near the top of the tree; has no hairs on the back of its twigs (hint: look between the needles near the end of a branch). White spruce prefers well drained, upland sites. Picea mariana (black spruce) - small oval cones often located along trunk and at the top of the tree; tiny red-brown hairs on the backs of twigs between needles (try a camera zoom or hand lens to see). Black spruce prefer low lying areas with more moisture like bogs or near wetlands.

  • 2020 Forest Action Plan

    2020 Forest Action Plan

    Alabama’s Forest Road Map 2020 The Forest Action Plan of the Alabama Forestry Commission Est. 1924 Welcome from the state forester Rick Oates, State Forester t is interesting how time modifies your perspective. Ten years ago, while working for the Alabama Forestry Association, I was asked to provide feedback in the development of the 2010 Alabama Forest Action Plan, Forests at the Crossroads. At the time I did not fully understand the importance of the Forest Action Plan to our state’s forest resources. IFast forward ten years and I am now the State Forester of Alabama, with a much better understanding of what this doc- ument means to the state. I now have the responsibility of updating this important plan. As such, it is with pride that I offer the 2020 Alabama Forest Action Plan, Alabama’s Forest Roadmap as a guide for all forestry stakeholders to reference over the next decade. This guide will serve as a tool to help our state better understand and manage this amazing resource. Alabama is blessed with abundant forest resources – 23.1 million acres - which cover more than two-thirds of the state. These forests improve water and air quality, provide wildlife habitat, support a growing forest industry and help provide jobs across the state. Without these forests Alabama would be a very different place. As such, we want to see forests remain as working forests in order to continue to accrue these important benefits. That is not to say there are not challenges associ- ated with our forest resource, but the assessment and strategies discussed in this document will be instrumental in raising awareness, implementing solutions and taking a step towards achieving this goal.
