English ivy invades Pacific Northwest forests

What’s wrong with a little ivy? Plenty. The photo with this post was taken recently in Olympic National Park, demonstrating that invasive species know no boundaries. This was only a small piece of the infestation, which was killing and pulling over trees and completely destroying the native plants growing under the trees. This immense spread of ivy has very little value for wildlife, unless you’re a rat.

Native to Europe, English ivy and similar cultivars were introduced to North America by early settlers who prized it for ornamental purposes. It continues to be widely planted as an ornamental, according to the Invasive Plant Atlas of the United States. Because of its shallow, mat-like root system, ivy is a poor choice for controlling erosion, such as on hillsides.

“But I only have a little,” you say? That’s how this started out. English ivy spreads aggressively both vegetatively and by bird-disbursed seeds. There are a number of different varieties, all invasive and all brought in as ornamentals.

Getting rid of ivy

Spraying is challenging because ivy has a thick, waxy leaf, but there are some herbicides listed for use (always follow label instructions). Fortunately, English ivy pulls up (roots and all) pretty easily, so with a little elbow grease you can make good strides in eradicating it. You should wear gloves and a dust mask for this, for the sake of comfort. For ivy that is growing up and strangling trees, you don’t have to pull it all off the tree (which could damage the bark). Instead, pull the ivy off the tree up to shoulder height, making sure to sever all stems growing up the tree. Without ground contact, the remainder up the tree will die. Then work on pulling the stuff on the ground back from the tree, pulling it up by the roots. Here are two Pacific Northwest-oriented fact sheets about controlling English ivy:

Winter weather can mean chilly temperatures, freezing winds, and snow in many parts of Washington. While we can choose to stay inside or bundle up and venture forth, trees don’t have that option; they withstand the elements as best they can. You can help your trees during this challenging part of the year by following a few suggestions offered by the International Society of Arboriculture (ISA).

  • Put composted organic mulch under your tree in the fall or early winter to help retain water and reduce temperature extremes. A thin layer of mulch will act like a blanket and give the tree’s roots a little extra winter protection.
  • Give your trees a drink. Winter droughts require watering as much as summer droughts. If temperatures permit, an occasional watering during the winter on young trees can be a lifesaver. But be sure to water only when soil and trees are cool but not frozen.
  • Prune your trees. Winter is actually one of the best times to prune because it is easier to see the structure of the trees without their leaves. But limit pruning to deadwood and poorly placed branches in order to save as many living branches as possible. Learn how to prune correctly by taking a pruning class, reading a book, or visiting a website.
  • Prevent mechanical injuries. Branch breakage or splitting can be caused by ice and snow accumulation, or chewing and rubbing by animals. Prevent problems on young trees by shaking heavy snow or ice from branches and wrapping the base of trees in a hard, plastic guard or metal hardware cloth (metal flashing). Wrapping trees with burlap or plastic cloth also can prevent temperature damage. Just remember to remove the wraps and guards in the spring to prevent damage when the tree begins to grow again.

To get the best advice for tree care, contact a local certified arborist. For more information on tree education, visit www.treesaregood.com.

Dec. 18 deadline fast approaching; apply now for your 2016 urban & community forestry grants

December 1, 2015
With a grant from DNR’s Urban and Community Forestry Program, the City of Tacoma’s Hilltop neighborhood planted trees in celebration of Arbor Day.

With a grant from DNR’s Urban and Community Forestry Program, the City of Tacoma’s Hilltop neighborhood planted trees in celebration of Arbor Day.

DNRs Urban and Community Forestry Program is pleased to announce our grants for 2016. There are three big changes to the grants this year – we have increased the total amount of dollars that can be requested by applicants, the grant applications are now in fill-able .pdf forms that can be downloaded from our website, and applicants have the option to submit their grant proposals electronically by email.

In previous years, our grants had open narrative where applicants were asked to describe their project within a five-page limit. However, the new fill-able forms are pre-formatted with a series of questions which applicants are required to answer within the spaces provided.

This year’s grants are available in three categories:

  • Community Forestry Assistance (CFA) Grants (download the RFP and Grant Application)
    • Acceptable projects should focus on urban forestry program development or innovative programs that educate staff, the public and decision-makers about the benefits of trees and/or proper tree care and management. Examples include but are not limited to: developing urban forestry management plans, tree ordinances, policy manuals, tree canopy analyses, website development, and curriculum development. Match (in-kind or financial) is required.
  • Tree Inventory Grants (download the RFP and Grant Application)
    • Tree inventories are a critical tool for urban forest management. A public tree inventory will be performed on behalf of successful applicant communities by a qualified consultant through a contractual agreement with DNR. No money changes hands, however, a Memorandum of Understanding between DNR and successful applicants is required. Successful communities must provide a report that describes an expected course of action toward community forest management within one year of receiving the inventory data.
  • Tree Planting Grants (download the RFP and Grant Application)
    • These grants are only available to communities who have earned the Tree City USA Award, as this designation is a minimum measure of cities’ capacity, expertise, and commitment to ensure that trees are properly planted and cared for. A 3-year maintenance plan and planting inspections by an ISA Certified Arborist are required. Match (in-kind or financial) is required.

The Community Forestry Assistance and Tree Inventory Grants are available to tribal governments, educational institutions, 501(c)(3) non-profit organizations and local governments such as cities, towns, and counties in Washington state. The Tree City USA Tree Planting Grants are only available to Washington cities and towns that have earned the Tree City USA Award, or to communities that are actively pursuing the Tree City USA designation and intend to apply for Tree City USA status in December 2015.

Grants are due by 4:00 PM on Friday, December 18, 2015. Please contact the grant coordinator, Linden Lampman at 360-902-1703 or linden.lampman@dnr.wa.gov for any questions about the 2016 applications.

The dispute over natural vs artificial trees continues

November 28, 2015
Real Christmas trees are a renewable resource. Is your artificial tree? Photo DNR

Every holiday season there are debates about which is the better choice – a real or artificial Christmas tree.

As an agency that leases land to tree farmers, manages the state’s urban forestry program, and employs a good number of foresters, we may be a bit biased. Still, here’s our attempt to keep you informed and dispel some common myths around the topic.

Myth 1: You save forests by using a fake tree. Yes, the U.S. Forest Service issues a small number of permits to cut wild trees, but most of the Christmas and other types of holiday trees you purchase are grown on farms just like any other agricultural crop. Because real Christmas trees are usually grown as a crop – they even call them ‘Christmas tree farms’ – you are buying a harvested product grown for this purpose.

Myth 2: Real trees aggravate allergies. A pine tree allergy is relatively uncommon, according to the American College of Allergy, Asthma and Immunology and real trees clean pollutants from the air as they grow.

Myth 3: Fake trees are fireproof.  Artificial trees advertised as “flame retardant” can resist flames for a period time, but when they do burn, they will emit significant heat and toxic smoke containing hydrogen chloride gas and dioxin. Take care no matter which tree you choose.

Myth 4: Real trees are a fire safety hazard. To minimize your risk, keep your tree freshly watered every day, use new lower-heat LED lights if you can, keep open flames away and dispose of the tree before the needles become brittle.

Myth 5: Fake trees are better because you can reuse them. Each year, municipalities reuse millions of real Christmas trees as mulch or wood chips. Natural trees are also 100 percent biodegradable. At some point, a fake tree wears out and ends up in a landfill (they aren’t recyclable or biodegradable).

Myth 6: Real trees cost too much. In Washington, most locally grown trees cost between $20 and $45 while a plastic tree costs from $100 to $300 depending on height and quality. You’ll have to use an artificial tree many years to break even. In any case, buying your tree locally helps support the fiscal health of your community.

Myth 7: Real trees have pesticides and chemicals on them. Tree farmers use chemicals only when needed and follow instructions made by the Environmental Protection Agency, the U.S. Department of Agriculture, and Food and Drug Administration. Plastic trees crafted outside of the United States may not have similar oversight. Know that lead dust from artificial trees can be harmful, especially to children.

Myth 8: Real trees are a hassle and a mess. Yes, they do need to be watered each day, but what is a half of a minute between friends? Yes, when you move the tree in and out of the house, you will need to vacuum. Hey, you probably needed to do it anyway. Plus, what says “clean” better than the scent of a fresh tree?

Myth 9: I can cut a tree on state lands. No, it’s illegal to cut trees from state trust lands. These trees need to grow to build future public schools in our state, as well as provide wildlife habitat and clean water and air.

Myth 10: No one cares if my tree is real or fake. Which sounds like more fun – picking out a fragrant, live tree with friends and family or waiting in a checkout line to buy a plastic replica of a tree? And, since most real holiday trees are grown on family-owned tree farms, purchasing a real tree makes an important economic contribution that matters to many rural Washington communities.

No need to burn outdoors; there are better options

November 21, 2015

Fall and winter can bring rough weather conditions that wreak havoc with roadways, homes, business and utilities. Storms can quickly create hazardous trees or limbs but there’s no need to compound the adverse event by raising the risks of a runaway wildfire. When you need to clear away yard and tree debris after a storm, think about options other than outdoor burning.

Outdoor burning is a leading cause of wildfire ignitions. If you must burn, know the rules, and choose the right weather for burning. If you have a burn barrel, don’t use it. In fact, just get rid of it – burn barrels are illegal in Washington state.

Fortunately there are alternatives to burning, such as chipping and composting, which are easy and practical ways to dispose of many organic materials or convert them to another use.

Alternatives to outdoor burning 

  • Compost it.It’s a practical and convenient approach for disposing of forest debris. Any vegetable matter can be composted. Organic material, such as fallen leaves, grass clippings, weeds, and the remains of garden plants, make excellent compost. Used as mulch for paths where it will eventually decompose and become compost to use in your garden. Check with your local county extension office, city, or county for schedules of composting classes.
  • Chip it.Turn large branches and debris into mulch. If you don’t already own a chipper, check with your local equipment rental agency. Invite your neighbors to join in to make it more cost efficient for everyone.
  • Use curbside pickup.
  • Take it to an approved landfill that accepts forest debris. Many counties have forest debris waste composting facilities.

Also, outdoor burning is a cause of smoke and certain pollutants. This smoke can be unhealthy, because the small particles in smoke are so tiny they can easily get into your lungs. People most at risk are children, patients with respiratory illnesses, and adults over 65 years old. Visit the Department of Ecology’s air quality website to find out if your local clean air agency has issued a burn ban and other advice.

Don’t risk burning

The biggest human cause of wildfires in Washington is outdoor burning. These escaped wildfires are investigated and, if found guilty, you can be fined. If burning is allowed in your area, the only material that can be burned is natural vegetation grown on the property where the burning occurs. And, be sure to check DNR’s webpage on silvicultural outdoor burning.

Getting a permit to gather firewood on DNR-managed state trust lands

November 19, 2015

Cutting firewood on

People often ask DNR if they can cut their own firewood on the forested state trust lands we manage. Generally, we provide places for you to cut firewood from downed wood or slash following timber harvests. Unfortunately, we don’t have as many of these opportunities as you might think.

DNR allows firewood cutting only when a timber harvest area has enough leftover downed wood or slash to make it worthwhile for you to go all the way out there. Many sites may have this left-behind wood but not enough for people to harvest for firewood.

Why do we insist on keeping some of this down wood around?

Because DNR manages forested state trust lands for habitat, as well as revenue production, a certain amount of the snags, downed wood and stumps left after a timber harvest must remain for birds, mammals and other critters. Habitat management is a key component of our State Trust Lands Habitat Conservation Plan.

Another factor limiting our supply is that the commercial timber harvesters who bid on trust lands timber are using more of the branches and stumps these days, so there’s less left behind to gather for firewood.

Check this web page to find out where DNR firewood gathering permits are still available. You’ll also find instructions for where and what to gather.

Some of the federal lands in Washington issue permits to gather firewood for personal use:

It is a violation of state law to cut down trees or take firewood from state trust lands without permission from DNR.

Geographic information systems (GIS) — the technology that helps us see the world around us in new ways — is in the spotlight today, November 18 — also known as “GIS Day.” Among the many events bringing together GIS professionals, students, and the general public to learn about and discuss the impact of this technology is an all-day conference at the Washington State Capitol today. Washington State Joint Agency Day features technicians from more than two dozen state, county and city agencies who gather to explain how they use GIS in the public’s interest and to save time and money. DNR, for example, uses GIS to reveal geologic hazards, map streams, route trails, track the spread of invasive species, and map marine vegetation.

DNR offers its trove of GIS data about forestry, geology, wildfire, wildlife and more to the public for download at no charge.

To see a real-world application of GIS data, visit DNR’s Washington Geological Information Portal where you can toggle multi-layered maps to find locations of major earthquake faults, lahar and tsunami evacuation zones, underground geologic formations, and more.

Homeowners have two good reasons for caution as fall storms encroach your property. Beware of residual hazards from storm-damaged trees, and roving “tree cutters” who may not have the best interests of you and your trees in mind.

Five tips to stay safe around storm-damaged trees

  1. Never touch or attempt to remove fallen limbs from downed or sagging power lines; always report downed lines to your local utility company.
  2. Keep away from areas where uprooted trees may have damaged underground utilities.
  3. Avoid walking underneath trees that have broken limbs dangling.
  4. If you need to inspect a tree after a storm, do not walk underneath its suspended branches or leaning trunk. Approach a leaning tree from the opposite side of the direction it is leaning. Binoculars are great for inspecting trees from a safe distance.
  5. Refrain from doing tree work yourself. Pruning large limbs or removing trees is dangerous business that requires specialized equipment and training.

After storms that cause heavy damage to trees, be wary of approaches from unskilled “tree cutters.” These individuals may pressure homeowners into costly and unnecessary work, cause additional property damage due to their lack of expertise or training, or put homeowners at risk by operating without proper licensing or insurance coverage.

Five more tips to ensure that you, your property, and your trees are cared for properly

  1. Hire a company that is licensed, bonded and insured. Look to see if it is certified by the International Society of Arboriculture (ISA).
  2. Seek at least three estimates; ask for copies of the estimates in writing.
  3. Never put down a deposit for work without a signed contract that includes the company’s refund policy.
  4. Ask for references, and check them.
  5. Reject any company that recommends “topping” your tree. Don’t top trees!

You can always contact DNR’s Urban and Community Forestry Program for additional guidance.

Green jobs benefit early career workers in Washington

November 3, 2015

A recent research project evaluated stress-recovery and personal effectiveness for young people who work in conservation jobs.  The research project explored how an outdoor work environment (including urban forest settings) may serve as a path to personal resiliency (through job opportunities, peer engagement, and skill building) and provide healing opportunities.

 

Washington Conservation Corps (WCC) is an environmental service program for young adults supported by the federal AmeriCorps service program. Corps members are 18 to 25 years of age, and participate in service work in small crews to restore natural resource sites. WCC engages approximately 300 people each year, a minority of whom are veterans. This study followed a cohort of approximately 270 WCC members who served for a year from autumn 2013 to autumn 2014.

 

The study was funded by the USDA Forest Service and Washington State Department of Natural Resources, with collaboration by the Washington State Department of Ecology. Dr. Kathleen Wolf from the University of Washington and Elizabeth Housley from OurFutureEnvironment Consulting LLC conducted the study.

 

Overall, the corps members entered the work program in quite good health compared to national standards, and yet research results show their perceived stress was further reduced after a year’s service. Returning second year members reported better perceived health and higher perceived leadership ability compared to new members.

 

Employment by organizations such as WCC can engage veterans and other early career adults in a socio-ecological projects where the benefits of nature experiences are coupled with opportunities to exhibit mastery, recover from stress and anxiety, and gain other positive markers of personal resiliency.

 

One possible outcome of this study might be to introduce outdoor work as a therapeutic activity for young adults, including younger veterans. If so, careful planning of work tasks to align with more diverse physical abilities would be important.

 

The technical report or a two page results summary  are available online. Or visit the Green Cities: Good Health web site for more information about the social and human health benefits of nature in cities.

It’s no trick: The bats at DNR’s Woodard Bay are a treat

October 31, 2015

As guardians to the home of the largest bat-breeding colony found in the State, DNR wants you to know that their presence is a real treat.

Bats are important for keeping insect populations in balance. The yuma myotis and little brown myotis bats at Woodard Bay eat mostly smaller insects such as mosquitoes, midges, and flies. They can consume up to 600 of them in just one hour.

Woodard Bay Natural Resources Conservation Area is open year-round, but summer is the time for bat fans to visit the newly restored site to watch the bats emerge at dusk from the old logging pier that they call home. Wait until after April when bats will return by the thousands to roost.

One of the informative signs that you can visit at Woodard Bay.

One of the informative signs you can visit at Woodard Bay Natural Resource Conservation Area, near Olympia.

Residents from Henderson Inlet to Olympia, Tumwater, and Lacey benefit from their bug-devouring ways. Locations as far away as Capitol Lake, Black Lake, Long Lake and Pattison Lake are confirmed feeding sites for this colony.

Chances are, however, that wherever you live in Washington you’ve got local bats treating you to summers with fewer bugs.
