State Bolsters its Defense Against Urban Forest Pests with New Guidelines

OLYMPIA — Pests looking to make their homes in Washington’s urban forests may now face a stronger defense, thanks to a new resource released this this month by the state’s Invasive Species Council.

The Washington State Urban Forest Pest Readiness Playbook, published in partnership with the Washington State Department of Natural Resources (DNR), contains guidelines that towns, cities, counties and urban forestry programs can follow to address the threat of forest pests, which are estimated to cost local governments across the country an estimated $1.7 billion each year.

Sequoia Mourned at Council Meeting

PORT ANGELES — Ten speakers lamented the felling of the Lions Park sequoia this week in the first City Council meeting since the tree was cut.  They decried Tuesday the controversial decision to cut the 42-year-old redwood on the morning of Jan. 3, a day not announced beforehand.

Council member Lindsey Schromen-Wawrin said the city failed the “don’t-make-little-kids-cry test for good government,” referring to two girls, 5 and 3 years old, who live near the park and cried when a city crew cut the 110-foot conifer before 8 a.m.

Forest Management Underway at the Lyre

Throughout the remainder of the summer, visitors of the Lyre Conservation Area may notice activity and/or hear noise from equipment and tools, such as chainsaws. As part of the Land Trust’s ongoing work to sustainably steward and restore the 280-acre conservation area, which includes shoreline, an estuary, kelp beds, meadow, wetlands, recovering timberland, and mature second growth forests, we recently contracted Peninsula Urban Forestry to conduct a 15-acre “accelerated succession” project within the conservation area…

Pretty Picky for a Generalist: Impacts of Toxicity and Nutritional Quality on Mantid Prey Processing

Prey have evolved a number of defenses against predation, and predators have developed means of countering these protective measures. Although caterpillars of the monarch butterfly, Danaus plexippus L., are defended by cardenolides sequestered from their host plants, the Chinese mantid Tenodera sinensis Saussure guts the caterpillar before consuming the rest of the body.

We hypothesized that this gutting behavior might be driven by the heterogeneous quality of prey tissue with respect to toxicity and/or nutrients…

Impact of an Invasive Insect and Plant Defense on a Native Forest Defoliator

Eastern hemlock (Tsuga canadensis [L.] Carriére) in the United States is threatened by the invasive hemlock woolly adelgid (Adelges tsugae Annand). The native hemlock looper (Lambdina fiscellaria Guenée) also appears to have played a role in previous population declines of this conifer. Although these two insects co-occur in much of the adelgid’s invaded range, their interactions remain unstudied.

We assessed looper performance and preference on both uninfested and adelgid-infested foliage from adelgid-susceptible hemlocks, as well as on uninfested foliage from an eastern hemlock that is naturally adelgid-resistant…

Hemlock Woolly Adelgid Alters Fine Root Bacterial Abundance and Mycorrhizal Associations in Eastern Hemlock

While the impact of aboveground herbivores on plant biomass and fitness has received considerableattention, there has been far less research on the corresponding belowground impacts. The belowgroundeffects of aboveground feeding may be particularly noticeable for invasive and/or outbreaking herbivorespecies that reach high densities and can cause major damage and sometimes death.

The hemlock woollyadelgid, Adelges tsugae, is an invasive pest on the eastern seaboard of the United States that feeds on anative shade-tolerant conifer, the eastern hemlock Tsuga canadensis. Trees rapidly decline and diefollowing infestation, and the invasion of this insect has devastated hemlock populations from Georgiain the south to Maine in the north…

State crew shaping up Bremerton’s trees

BREMERTON — Trees in the city are getting some special attention this month.

A state crew from the Department of Ecology has been traversing Bremerton’s parks and boulevards, trimming the city’s tree population and ridding some areas of noxious weeds. The goal of the work is improved air and water quality, as the trees soak up both stormwater from running into Puget Sound and carbon dioxide in the air.

Plus, as urban forestry crew leader John Longsworth points out, they have a big impact on a city’s quality of life…

Prey Handling of Toxic and Non-toxic Lepidopteran Prey by Chinese Mantid, Tenodera sinensis

Monarch caterpillars, Danaus plexippus, sequester toxic cardenolides from milkweed plants. This defense is effective against most predators, but the Chinese mantid, Tenodera sinensis, is able to consume them without any apparent ill effects. It has been shown that mantids consume monarch caterpillars by gutting them, allowing the gut material to fall from the prey without further consumption.

They do not engage in this behavior when consuming non-toxic European corn borers, Ostrinia nubilalis, or wax worms, Galleria mellonella, suggesting avoidance of prey toxicity. We tested the prey toxicity hypothesis and the alternative hypothesis that the gutting behavior reflects a more generalized avoidance of lower-quality (i.e., less-nutritive) plant material…

Wool-Wearing Villains

Clashing, crashing, smashing–the once hearty hemlock heaves its now crippled form to the forest floor. What brings this mighty tree to its knees? Was it the axe man, his barrel chest booming with each thunderous blow? Was it the furious gusts of a gale going through the eastern hemlock stand, singing songs of sorrow?

NAY!!!  The culprit creeps covertly along unsuspecting branches, before driving deep its dark feeder into the base of a hemlock needle: an invasive insect, a vile villain, the herald of misfortune for hemlocks all along the eastern lands. They drain the vigor from their victims not for vengeance, but for an unrelenting and unreasonable will to have all hemlocks bow before their kind. It’s the hemlock woolly adelgid! These white wool-wearing devils must have their advance stalled, so I study their ways…

Experimental Forests as a Gateway Protection of Ecosystem Services Through Sustainable Forest Management

Individuals around the globe are joining the initiative to keep a “green space.” By keeping an area growing with plant life, photosynthesis and all the marvelous components associated help to better the environment through temperature regulation, conversion of carbon dioxide to oxygen, sequestration of carbon, and in some cases, erosion control.

The idea is to not only help offset the carbon foot print we ‘stomp’ on the earth as continuous consumers, but to provide benefits that are reduced as we increasingly impact and change the surrounding landscape. We will feel the unmitigated effects of global climate change as deforestation continues and ‘city trees’ disappear because we are less protected without our living filters…
