Look up! It’s the forest canopy (Part 2)

The canopy layer in the forest—the interacting tree crowns that create a remarkable maze of three-dimensional spaces between and on the branches—is a habitat niche with specialized functions for many species of wildlife. The surfaces of these branches and leaves provide shelter and food for a wide variety of arboreal (forest canopy inhabiting) mammals, birds and insects.

Arboreal mammals

Truly arboreal mammals are not as numerous as bird species, but are important members of the forest wildlife ecosystem. Our native conifer squirrels are the Douglas and red squirrels (members of the genus Tamiasciurus), locally known as chickarees. These two species are actually very similar, but occupy different habitat regions. Douglas squirrels are associated with wetter, westside type forests dominated by Douglas fir and hemlock. Red squirrels live on the drier and colder east side, as well as in Rocky Mountain forest types we have in Northeast Washington. Both are common and important mammal species directly tied to the forest canopy as conifer specialists, actively harvesting and caching cones each year. Who among us woods walkers hasn’t been scolded by one of these little dervishes?

Fungi (mushrooms), which help trees grow by adding root absorptive surface to trees, is food for squirrels. The squirrels spread spores throughout the forest through their feces. Flying squirrels occupy a similar niche, but work the night shift, often foraging on the ground for mushrooms to cache. For this reason, flying, Douglas and red squirrels can be considered keystone species in forest ecosystems, e.g., species whose presence has far-reaching impacts. These squirrels need canopy to provide hiding places and food, but also need down logs for cache sites, and woody cavities in snags for denning. Habitat for these squirrels also includes low branches for resting and eating cones dropped to the ground.

Titanium alloy golf clubs can cause dangerous wildfires, according to UC Irvine scientists.

National Bird Feeding Month

February 20, 2014

bird bro!Even though February is a winter month, not all birds fly south to find warmer weather. In fact, February is National Bird Feeding Month. Time to dust off those bird houses and crack the ice on the bird bath because our feathered friends are here and they are hungry. Whether you are a seasoned feeder or just wanting some natural music in the back yard, this is the month to do it.

Several different types of birdhouses and feeders cater to a wide variety of birds. Knowing what birds you might be catering to is a great place to start. There are several sites that can help you find what you are looking for. Here is a quick rundown of a few of the basics types of feeders you can use.

Feeder types:

  • Tube Feeder: Good for fending off squirrels and feeding chickadee-like birds
  • Hopper Feeders: Good for multiple birds at once, it will accommodate all types, even larger birds.
  • Suet Feeder: Good for attracting insects to organically feed woodpeckers and the like.
  • Thistle Feeder: Good for small-beaked birds and keeping bigger animals out.
  • Ground Feeder: Good for all types of birds, even those who would not fit on a hung feeder.
  • Nectar Feeder: Good for long-beaked birds like hummingbirds

When setting up a feeding station, keep in mind the location and what you are putting into the feeders. If you are looking to excite the local aviary population, add some variety to the diet. Mix in a few berries or bits of fruit here and there or give them a reason to stick around with some peanut butter. Just having a different seed mix every once in a while can make all the difference.

Due to the cold in the winter, most of the natural food supply is exhausted during the winter. So have a good time making a birdhouse and then fill it up for all to enjoy.

Here is a quick FAQ with some of the dos and don’ts of winter bird feeding if you would like to get more involved.

A few scary facts for Halloween 2013

October 31, 2013

If the parade of costumed tricker-treaters coming to your door tonight or the endless reruns of horror movies on TV these past few weeks (or today’s close-up photo of snake) are not enough to give you a fright, here are some scary facts about the state of the environment in Washington State, with an emphasis on biodiversity.

  • Approximately 33 percent of the Puget Sound’s 2,500 miles of shorelines have been armored with bulkheads and other structures to protect homes, ports, marinas, roads and railways, and other property. More than half of the shoreline in the central Puget Sound has been modified by port development, armoring of beaches, and other uses, causing significant loss of habitats important to beach and nearshore species.
  • More than half of the Columbia Plateau Ecoregion (roughly the area known as the Columbia Basin) has undergone conversion from its shrub-steppe landscape to cropland. What remains is a fragmented shrub-steppe, which compromises the habitat of many species that rely on this type of habitat.
  • More than 90 percent of the original Palouse grasslands in Washington have been converted to agriculture, housing or other uses. A number of plant species once common throughout the Palouse now hang on in small, isolated remnants.

What’s so important about biodiversity?

Native species (such as shellfish, salmon and Douglas-fir) and their ecosystems contribute billions of dollars to fisheries, timber harvests, outdoor recreation and other sectors of our state’s economy. Native ecosystems also provide clean water, natural flood control, and habitats for fish, plants, and wildlife.

To help protect these important native habitats that help nurture biodiversity, DNR manages a statewide network of Natural Area Preserves and Natural Resources Conservation Areas. Many of these areas represent the finest natural, undisturbed ecosystems in state ownership; they also protect one-of-a-kind natural features unique to this region, such as the Mima Mounds in Thurston County or Selah Cliffs in Yakima County.

Take Our Daughters and Sons To Work® at DNR

Yesterday the Washington State Department of Natural Resources (DNR) celebrated Take Our Daughters and Sons To Work® Day with the children of state employees.

This year, the Take Our Daughters and Sons To Work® Foundation partnered with the National Association of State Foresters to introduce children to careers in forestry. Almost a hundred kids came out to learn about the jobs we do at DNR, the Department of Fish and Wildlife, and the Washington Department of Agriculture.

For half a day, the Natural Resources Building here in Olympia was transformed into an education fair featuring trees, bugs, and geodes. Kids had an opportunity to learn how foresters work in the woods and try to stump the forester with their questions. They got up close with bugs while learning about forest health from one of DNR’s entomologists.

At the Washington Geology Library, children learned the life-cycle of a rock and identified special rocks, from geodes to the Washington state gem:petrified wood. Many kids put their directional skills to the test by learning to use a compass and trying to complete the orienteering course mapped out by DNR’s recreation staff. They were given a noble fir seedling from DNR’s Webster Nursery and practiced proper planting with the Washington Conservation Corps Urban Forestry team.

Participants also learned how Geographic Information System (GIS) specialists make maps and use technology to help DNR teams fight wildland fires.

They also experienced what it’s like to be a DNR firefighter by meeting some of the team, trying on personal protective equipment, and meeting Smokey Bear, who paid a special visit. Even Commissioner of Public Lands Peter Goldmark came down to meet the children, thank the volunteers, and snap a quick photo with Smokey.

DNR is happy to have had the opportunity to recruit our future generations of state land managers. If you are interested in finding out about the several types of careers that DNR has to offer, visit our jobs page and apply to work with DNR today.
