Habitat Assessment

Pollinator Biology and Habitat in California: USDA-NRCS: Technical Note

This technical note is intended to be used during conservation planning as a guide to provide suitable habitat for pollinators, primarily native bees, but also including managed bees, for management practices and facilitating practices that restore, enhance, or manage lands in agricultural settings.

 

Habitat Assessment Guide for Pollinators: Yards, Gardens, and Parks

Landscaping for pollinators is one of the easiest ways for urban, suburban, and rural residents to directly benefit local wildlife. Schoolyards, community gardens, back yards, corporate campuses, rain gardens, and neighborhood parks all have the potential to meet the most basic needs of pollinators, including protection from pesticides, and resources for foraging, nesting, and overwintering.

Site preparation is one of the most important and often inadequately addressed components for successfully installing pollinator habitat. These guidelines provide step-by-step instructions, helpful suggestions, and regional timelines & checklists for preparing both small and large sites.

 

422A Hedgerow Planting, Pollinators: Central Valley, Central Coast, Southern California

These region-and state-specific guidelines provide in-depth practical guidance on how to install and maintain nectar- and pollen-rich habitat for pollinators in the form of wildflower meadow plantings/conservation cover (NRCS Conservation Practice 327) or linear rows of native flowering shrubs/hedgerow plantings (NRCS Conservation Practice 422). Seed mixes and plant recommendations for each region are included in the appendix of each guide.

Seed mixes and plant recommendations for each region are included in the appendix of each guide. 

 

Insectary Cover Cropping in California

Insectary cover cropping is the practice of growing single species or diverse mixes of broadleaf herbaceous plants and allowing them to bloom to provide pollen and nectar resources that support populations of native bees, honey bees, and the insects that attack crop pests.

 

Cover Cropping for Pollinators and Beneficial Insects

This 16-page bulletin will help you use cover crops to encourage populations of pollinators and beneficial insects on your farm while you address your other resource concerns. It begins with a broad overview of pollinator and beneficial insect ecology, then describes cover crop selection and management, how to make cover crops work on your farm, and helpful and proven crop rotations. It will also touch on the limitations of cover crops and pesticide harm reduction, among other topics.

 

Establishing Pollinator Meadows from Seed
Establishing wildflower habitat for pollinators is the single most effective course of action to conserve pollinators that can be taken by anyone at any scale. These guidelines provide step-by-step instructions for establishing pollinator meadows from seed in areas that range in size from a small backyard garden up to areas around an acre.

 

Estimated Costs to Establish Pollinator Hedgerows

This fact sheet outlines the estimated costs of establishing hedgerow habitat for pollinators. Pollinator hedgerows are diverse linear plantings of native flowering trees, shrubs, perennial wildflowers and grasses designed to provide foraging and nesting habitat for pollinators. These estimates represent average costs of establishing hedgerows from transplants, and are derived from a series of pollinator hedgerow habitat projects throughout the United States. Actual costs vary from project to project and region to region.

 

Estimated Costs to Establish Wildflower Plantings Using Solarization

This fact sheet outlines the estimated costs of establishing wildflower habitat for pollinators using a method referred to as solarization. These cost-estimates are applicable to relatively small-scale (e.g., <1 ac) on-farm habitat plantings. They represent average cost ranges and are derived from a series of pollinator habitat projects across the United States that involved establishing conservation cover from seed. Specific costs will vary by project and by region.

Best Management Practices for Pollinators on Western Rangelands

Incorporating pollinators into rangeland management is essential to help maintain or recover pollinator populations and also maintain healthy rangelands for plants, wildlife, livestock, and the people who rely on them. While there is still much to learn, these BMPs provide actionable, practical recommendations that enables land managers to help conserve pollinators on public lands in the West.

 

Roadside Best Management Practices that Benefit Pollinators

These best management practices provide concrete steps that can be taken by any roadside management agency to improve roadside vegetation for pollinators. The BMPs cover management of existing habitat, including ways to modify the use of mowing and herbicides to enhance roadsides, and methods to incorporate native plants and pollinator habitat into the design of new roadsides.

 

Roadside Habitat For Monarchs: Monarch Butterflies, Weeds, and Herbicides

Roadsides provide more than just milkweed. They can also provide diverse nectar sources to feed adult monarchs and other pollinators—but ensuring that roadsides can continue to provide the best habitat requires some thought and care. This guide highlights best management practices to reduce the impacts of herbicides on monarchs.

It includes information on selecting habitat sites, as well as ways to maintain clean habitat by limiting and carefully managing pesticide use.

 

Smarter Pest Management: Protecting Pollinators at Home

Most of North America’s native bee species only forage over a distance of a few hundred yards, so with a little planning, your yard can provide a safe space for bees and other pollinators to thrive. All you need to give them are flowering plants throughout the growing season, undisturbed places to nest, and protection from pesticides. This Xerces Society guide will help you with the last item, managing yard pests in a pollinator-friendly way.

 

Smarter Pest Management: Pollinator Protection for Cities and Campuses

This Xerces Society fact sheet introduces to city and campus land managers the concept of integrated pest management (IPM), a system that emphasizes prevention first and seeks to eliminate the underlying causes of plant diseases, weeds, and insect problems rather than relying on routine use of pesticides.

 

Protecting Pollinators from Pesticides: Fungicide Impacts on Pollinators

From large farms to small backyard gardens, many people use fungicides to control plant pathogens. While insecticides have long been recognized as a threat to bees and other beneficial insects, fungicides have generally been assumed to be relatively harmless. Though most fungicide exposures won’t kill a bee immediately, a growing body of research suggests that some fungicides can cause subtle yet significant harm. This Xerces Society fact sheet delves into how these impacts on pollinators occur, and offers mitigation measures and alternative pest management strategies.

 

How to Reduce Bee Poisoning from Pesticides

Organic Pesticides: Minimizing Risks to Pollinators and Beneficial Insects

These Xerces Society guidelines provide a brief overview of how to select and apply pesticides for organic farm operations while minimizing pollinator mortality. Many of the practices outlined here for protecting pollinators also can help to protect beneficial insects such as parasitoid wasps and flies; predaceous wasps, flies, and beetles; ambush and assassin bugs; lacewings; and others. The presence of these insects can further reduce pest pressure and the need for chemical treatments.
