Establishing Pollinator Meadows From Seed

Posted on by Lilia Letsch

Author: The Xerces Society Date: 2015

To boost healthy populations of both wild resident bees and managed pollinators, the single most effective action you can take is to plant native wild flower habitat. This tangible course of action can be accomplished by anyone at any scale. The process behind establishing a wild flower-rich pollinator planting from seed consists of five basic steps:

  • Site selection
  • Site preparation
  • Plant selection
  • Planting techniques
  • Ongoing management

The steps outlined in this document are applicable to plantings that range in size from a small backyard garden up to areas around an acre.

Farming For Bees: Guidelines for Providing Native Bee Habitat on Farms

Posted on by Lilia Letsch

Author: The Xerces Society Date: 2015

The purpose of these guidelines is to provide information about native bees and their habitat requirements so that farmers can manage the land around their fields to provide the greatest advantage for these crop pollinators. These guidelines will help growers and conservationists:

  • understand how simple changes to farm practices can bene t native pollinators and farm productivity;
  • protect, enhance, or restore habitat to increase the ability of farmlands to support these bees; and
  • ultimately increase a grower’s reliance upon native bees for crop pollination.

Making small changes to increase the number of native pollinators on a farm does not require a lot of work. Subtle changes in farm practices can involve identifying and protecting nesting sites and forage, choosing cover crop species that provide abundant pollen and nectar, allowing crops to go to flower before plowing them under, or changing how pesticides are applied in order to have the least negative impact on bees.

Oregon Flora Plant Atlas

Posted on by admin

Author: Oregon Flora Project Dept. Botany & Plant Pathology, Oregon State University (various authors)

The Oregon Plant Atlas allows the user to generate customized plant distribution maps from herbarium specimen and observation data. The default search results displayed are “Flora vouchers”, specimens from the OSU Herbarium and selected vouchers from other herbaria. These serve as reference material for the upcoming Flora of Oregon. Any combination of available specimens or unvouchered observations can be mapped by selecting the appropriate checkboxes.

Guide to Placement of Wood, Boulders and Gravel for Habitat Restoration

Posted on by Lilia Letsch

Author: ODF/ODFW Date: 2010

This guide has been developed to facilitate the placement of large wood, boulders and gravel in a manner consistent with these principles and regulations in Oregon. These techniques, when done independently or in conjunction with other restoration activities, increase the channel complexity and diversity of habitat necessary to help restore and support a healthy aquatic ecosystem.

Restoring Rare Native Habitats in the Willamette Valley

Posted on by Lilia Letsch

Author: Campbell, B. Date: 2004

This guide is organized by the four priority habitat types: oak woodlands; wetlands; bottomland hardwood and riparian forests; and grasslands and prairies. A brief discussion of each habitat is followed by restoration considerations and techniques. References or sources of information are denoted by superscript numbers that refer to entries in the bibliography. Restorationists wishing to obtain additional information or delve more deeply into a topic may want to review these references.

A Landowner’s Guide for Restoring and Managing Oregon White Oak Habitats

Posted on by Lilia Letsch

Authors: Vesely, D. and Tucker, G. Date: 2004

The primary purpose of this Guide is to encourage private landowners to conserve, and when appropriate, actively manage Oregon white oaks that already exist on their property, and consider planting additional oaks. In the early chapters of the Guide, we describe some of the uses and benefits of this remarkable tree in hopes of motivating landowners to take action. An introduction to the ecology of the Oregon white oak is included so the reader can better understand how management practices are founded on aspects of the tree’s biology. Later chapters are designed to help landowners develop land management goals and understand the process of natural resource planning.

A Guide to Riparian Tree Planting in Southwest Oregon

Posted on by Lilia Letsch

Authors: Bennett, M. and Ahrens, G. Date: 2007

This publication is a step-by-step guide to riparian tree planting in interior southwest Oregon, including Jackson and Josephine counties and the noncoastal portions of Douglas County. Compared to other parts of western Oregon, this area experiences hotter, drier summers, and lower annual precipitation, which poses unique challenges for the survival and growth of riparian plantings. While some details apply mainly to this region, the principles discussed are broadly applicable to tree-planting projects in riparian areas throughout the Pacific Northwest.

Manual and Land Cover Type Descriptions: Oregon Gap Analysis, 1998 Land Cover for Oregon

Posted on by Lilia Letsch

Author: Killsgaard, C. Date: 1999

In its Acoarse filter@ approach to conservation biology, gap analysis relies on maps of dominant natural land cover types as the most fundamental spatial component of the analysis for terrestrial environments. For the purposes of GAP, most of the land surface of interest (natural) can be characterized by its dominant vegetation. Vegetation patterns are an integrated reflection of the physical and chemical factors that shape the environment of a given land area. They also are determinants for overall biological diversity patterns, and they can be used as a currency for habitat types in conservation evaluations
