Hear Dr. Sarah Luttrell talk about her work on evolution and speciation in the marsh wren (Cistothorus palustris).  Dr. Luttrell studies how evolution works by studying subspecies of birds.  She will examine how comparing multiple traits like plumage color, size and shape, vocal behavior, and genetics in marsh wrens has revealed an exciting pattern of evolution in this bird.  She received her Ph. D. in Biological Sciences in August 2017 from the University of Maryland, Baltimore County.

 

The program is sponsored by Friends of Dyke Marsh.  It is free and open to the public.

Review of The Humane Gardener, by Nancy Lawson

Reviewed by Ann Di Fiore

As a Fairfax Master Naturalist and Audubon at Home Ambassador, I am always on the lookout for books on native plant and wildlife gardening. The Humane Gardener (2017, 224 pp) offers insights on both topics, but what sets Lawson’s book apart from others is her emphasis on creating habitats that nurture all forms of wildlife. Interspersed with chapters on native plantings, creating habitat, and the benefits of decaying plant material are profiles of humane gardeners whose properties range from modest backyards to commercial farms.

Many of the principles Lawson lays out are well known to master naturalists: “Plant for all seasons and sizes” to address “diverse diners”; use “green mulch”—native grasses and groundcovers—rather than bark in between shrubs and trees to improve soil; choose straight species over cultivars; and don’t “love” –overwater and over fertilize—native plants.

Lawson urges us to be attentive to gardening activities that have tragic consequences for wildlife.  In a section entitled “Don’t Mow the Teenagers,”she warns us that mowing, pruning, and raking can cut short the life cycles of ground insects and other animals. Fritillary larvae, for example, crawl onto violet plants in early spring and, as Doug Tallamy puts it, “we murder them with our lawn mowers.”  Baby rabbits in hidden nests and other young animals are vulnerable as well.

When removing invasive plants from our properties, Lawson asks us to “triage” their removal to minimize adverse effects on wildlife that make use of these plants. Early blooming invasives may be the only available nectar sources to bees, fruiting shrubs like Amur honeysuckles may fill a significant part of a bird’s diet.

In The Humane Gardener, Lawson addresses an uncomfortable truth:  the wild creatures most gardeners want to support are songbirds and pollinators. Many other forms of wildlife we consider interlopers—enemies. She enumerates the cruelties inflicted by pest removal services, glue traps, even “humane” deterrents (predator urine, for instance, is captured from caged coyotes and other animals on fur farms). She advocates flexibility and a more generous perspective:  opossums and raccoons eat carrion, ticks, and slugs; rabbits devour dandelions; and moles and chipmunks till the soil, increasing its fertility.

In a world of shrinking natural spaces and biodiversity, Lawson asks us to reconsider our ideas of ownership and make room for all forms of wildlife.  Above all, she asks that we be conscious of the consequences of our routine gardening choices.  She promises that our gardens will be healthier—and more humane—as a result.

Join the National Audubon Society, National Geographic, BirdLife International, and the Cornell Lab of Ornithology in a yearlong celebration of birds

 

2018 is it the 100th anniversary of the signing of the Migratory Bird Treaty Act—legislation that saves countless birds’ lives—but birds are facing many new and serious threats. Audubon has teamed up with National Geographic, BirdLife International, and the Cornell Lab of Ornithology to officially make 2018 the Year of the Bird.

Throughout the year, these partners, along with more than 100 other participating organizations, will be celebrating birds while raising awareness about their troubles across all of our channels—magazines, television, social media, and more—with new editorial, content, and programs.

Help build a better world for birds by taking a simple but meaningful action each month. Count Me In gives you options for learning about some ways to participate.

Check out the official Year of the Bird website for others.

Family friendly volunteer opportunities: Restore habitat in Oakton and Vienna, 27 January

The Invasive Management Area (IMA) Program is hosting habitat restoration service opportunities on Saturday, 27 January, in Wayland Street Park in Oakton, and Borges Street Park in Vienna . See calendar for details of timing and requirements.

  • The minimum age to volunteer is 11. Please contact the IMA Coordinator for details.
  • Volunteers 13 and younger must be accompanied by an adult.
  • Students who need community service hours, please bring the form to be signed to your workday.
  • IMA workday forms must be received by noon the day prior to the event for weekday workdays, and by noon on Friday for weekend workdays.

The IMA Volunteer Program is a community-based project designed to reduce invasive plants on our parklands. This program gives volunteers an opportunity to connect with like-minded people while taking care of natural resources. Through IMA, you’ll protect the plants and wildlife of Fairfax County’s forests while spending time outdoors, meeting new people and restoring natural habitats.

IMA is more than just pulling weeds. It’s also habitat restoration and a long-term commitment to parks. Invasive plant species are difficult to remove and control, but with the help of IMA volunteers, undesirable non-native, invasive plants are removed and native plants are returned to the habitat. Native plantings take place in the spring and fall.

The IMA project began in 2006 with 20 sites. Since then, more than 35 acres have come under IMA management, and there are 40 active IMA sites. More acres have been treated and restored by contractors and staff.

Apply for Earth Sangha plant grants for spring 2018. Due 28 February

The Earth Sangha Plant Grant supports small-scale, citizen-led restoration efforts across Fairfax County. Twice a year, they accept applications for restoration projects on public lands in need of local-ecotype native plants. They will then offer a matching grant on plants purchased (essentially a buy-one, get-one free offer) good for one season up to a certain dollar amount. No project is too small, whether it’s a community-led invasive pull, or a larger project with multiple partners, they support thoughtful restoration efforts on public lands.

To read The Acorn article outlining the Plant Grant see here.

To take advantage of the Plant Grant. See the criteria and application below.

Selection Criteria

Projects should have the following:

  • Ongoing conservation or restoration work occurring on public lands in Fairfax County (projects outside Fairfax County will be reviewed, but our current focus is to support public lands in our home jurisdiction)
  • Letter of support from a relevant public agency (whoever owns or administers the area in question), an email is fine
  • Proposed plant list for the site in question (we can help you refine this, if needed)
  • Timeline for the planting
  • Plan for maintenance of the planting site

Click here for the Plant Grant Application

How to Apply:

Fill out the pdf form (see below) and email it to Matt Bright, [email protected] along with a letter of support from your agency sponsor and 2-3 photos of the site.

Spring Grant Period: For projects to be planted in Spring 2018. Applications due by February 28, 2018.
