Species Spotlight – Western Skunk Cabbage

Species Spotlight: Western Skunk Cabbage (Elgaria coerulea)

This month, we cast the Species Spotlight on Western Skunk Cabbage!

Western Skunk Cabbage, also called Swamp Lantern, is recognized by its bright yellow spathe and flower-covered spadix. If you’ve encountered one in the watershed, you know where the name comes from! The odor is a deterrent to humans but loved by pollinators.

While out exploring Land Trust properties, our Stewardship Team noticed a striking sight- bright yellow and green skunk cabbage pushing up through the snow. One of the earliest to bloom in the spring, this pungent native pollinator plant is a sign that winter will soon be behind us, and warmer days are ahead.

Description

Western skunk cabbage, also called Swamp Lantern, is often recognized by its bright yellow spathe and flower-covered spadix. It has been known to grow up to 5’ tall and 2’ wide with the largest leaves of any native plant in the region. If you have encountered Western skunk cabbage in a wetland, you know the name comes from its foul odor. This is emitted from the spadix, although the leaves can produce a similar odor when crushed.

While the scent is a deterrent for humans, pollinators are attracted to the plant for this very reason. Its primary pollinators include scavenging flies and beetles, particularly a tiny species of rove beetle.

Western skunk cabbage can be easily differentiated from the Eastern variant, which is typically dark purple. Additionally, Eastern skunk cabbage, like many other plants of the Araceae family, generates heat metabolically. Although it is a common misconception, Western skunk cabbage does not generate its own heat.

Habitat

In recent years, Western skunk cabbage has gained attention throughout parts of northern Europe as a highly invasive plant. It was introduced to the region in the early 1900s as an ornamental plant popular among gardeners. It has since spread into the local ecosystem, blocking drainage channels in parts of Britain and adversely impacting their woodlands.

In the Pacific Northwest, however, this is an important native plant that supports the health and proper functioning of stream habitats and forested wetlands. Beyond providing important resources to pollinators, it is a food source for various wildlife species, which consume the stem and seeds. Amphibians and insects take shelter under its large leaves, and its decaying foliage provides important nutrients to the soil.

Although Western skunk cabbage is not listed as endangered, a habitat in which it is one of three characteristic species is currently listed as imperiled. The Land Trust’s work to restore and protect stream and wetland habitats ensures that skunk cabbage, among other plants, can thrive in a healthy environment.

Ethnobotany

Skunk cabbage is moderately toxic and is not recommended for human consumption, as it contains crystalline shards of calcium oxalate. It has, however, been used medicinally through careful preparation to treat coughs, headaches, and respiratory ailments. It is also a great addition to Pacific Northwest gardens, helping to deter common pests like squirrels and raccoons.

As you venture out this spring, look for the bright yellow spathe pushing up through wet areas. You may just get to see (or smell) this beautiful native plant waking up, announcing spring is here!

Species Spotlight – Northern Alligator Lizard

Species Spotlight: Northern Alligator Lizard (Elgaria coerulea)

This month, we cast the Species Spotlight on the Northern Alligator Lizard!

The northern alligator lizard is one of only two lizards in Washington state with square scales and folds on the side of its body. Its dark eyes help differentiate it from the southern alligator lizard.

The northern alligator lizard looks exactly like one might think- akin to a baby alligator. It is known to be a bit secretive and is rarely seen in the open. Luckily, our Stewardship Manager Jake was able to spot this one up close while visiting one of our properties!

Physical Description

This is one of two alligator lizard species commonly found in Washington. Both species differ from other lizards in Washington in that they have square scales and folds on the sides of their body. Although the northern alligator lizard can vary greatly in color, it is typically gray-brown to brown with dark brown eyes. This is one way to differentiate it from the southern alligator lizard, which has yellow or gold eyes.

The northern alligator lizard can grow up to nearly 4 inches long and has a long tail, which it can easily shed if threatened by a predator. For example, the northern alligator lizard is often preyed on by house cats. In this situation, the lizard drops its tail, which will continue to wriggle around, distracting the cat and providing an opening to escape.

Tail loss can negatively impact its reproductive ability and make it more vulnerable to adverse environmental factors. However, in most cases the tail will regrow in a matter of weeks.

The northern alligator lizard has a long tail, which can be shed if threatened by a predator.

Habitat

The northern alligator lizard typically prefers cool temperatures and forested habitat, especially rocky openings, grassy areas, and woody debris. It is known for being adaptable to various conditions. Although it is not currently threatened, the northern alligator lizard can be impacted by large-scale habitat destruction with increasing development.

Habitat Restoration and Protection

Much of our work at the Nisqually Land Trust includes habitat restoration projects to restore and protect forested land. By acquiring forested areas, removing invasive plants, and planting native trees and shrubs, we work to create and conserve healthy habitat for the many species that call the Nisqually Watershed home.

Species Spotlight – Western Red Cedar

Species Spotlight: Western Red Cedar (Thuja plicata)

This month, we cast the Species Spotlight on the Western Red Cedar!

Western Red Cedar sapling at a Nisqually Land Trust planting near Ohop Creek

As we near the end of planting season, we are highlighting the Western Red Cedar.

This evergreen conifer has long been important in the Pacific Northwest. Culturally, it holds great significance for tribes across Western Washington, having been utilized for millennia in homes, canoes, fishing gear, art, medicine, and more. It is naturally insect- and fungi-resistant, and the wood is evenly grained, making it economically valuable. The Western Red Cedar also provides shade critical for salmon, keeping stream temperatures cool and allowing them to thrive.

This planting season, Nisqually Land Trust staff and volunteers have planted Western Red Cedar saplings, along with other native trees and shrubs, on one of our properties along Ohop Creek.

NLT Stewardship Manager Jake Pool noted that the Western Red Cedar is “not commonly replanted in wetland areas, and when logged it is often replaced with timber species.” One reason it can be difficult to replant is that it needs to be protected from deer and elk, as they like to eat it. Those who have planted with us over the years have noticed that we stake and tube the new trees and shrubs. In doing so, we provide extra protection for the saplings until they have grown tall enough to thrive.

Black bears and other small animals often strip Western Red Cedars for sapwood.

The Western Red Cedar is also heavily utilized by other wildlife. Jake captured the photo on the right, showing a Western Red Cedar on NLT property where a black bear had clawed open and chewed on the tree, stripping it for the sapwood underneath. Smaller animals, such as porcupines and squirrels also strip the bark to line their nests and for food.

The Western Red Cedar has been heavily impacted by climate change in recent years. While it is a member of the Cypress family, it is not drought tolerant as are other Cypress trees. Since it does not have a taproot, but rather a shallow and wide-spreading root system, it cannot extend deeper for water sources when moisture levels are low. As a result, it has suffered widespread die-off over the past decade in the Pacific Northwest with warmer temperatures and repeated droughts.

One of our greatest priorities for our properties is habitat restoration. For this reason, our Stewardship Team works to plant Western Red Cedars in areas we believe they can thrive, while also removing invasives to minimize competition for water resources.

Species Spotlight – Western Toad

Species Spotlight: Western Toad (Anaxyrus boreas)

This month, we cast the Species Spotlight on the Western Toad!

Western toad discovered on Land Trust property in Ashford, WA

Stewarding the land is not only about protecting and improving the land, but also observation. During recent summer work in the Nisqually Land Trust properties in Ashford, WA, known as Mt. Rainier Gateway, larger adult Western toads were found in culverts. If there are adults, there must be a breeding location nearby.  

A closer look at the maps led us to some ponds nearby that seemed like ideal habitat. These ponds are in the Nisqually Community Forest lands, a separate subsidiary non-profit of the Nisqually Land Trust. At first, walking up to the pond surrounded by subalpine meadow flowers and grasses yielded nothing in toads, but lots of pollinators enjoying the flowers. Once we got closer to the moist soil on the edge of ponds, the ground looked like it was moving amongst the foliage. We knelt down along an animal trail, and you could see hundreds of toadlets moving and hopping along the ground. All the ponds in the area had thousands of toadlets that had recently metamorphosed from their aquatic habitat.

Part of our stewardship on these lands is to bring the forest and meadows back to their natural functioning state. Most of the area had been planted densely in single conifer species of trees. Little diversity and low light levels at the forest floor does not produce a quality and diverse habitat for many species of wildlife and plants, which the toads and so many other animals need to do well.  

To restore good conditions, we thin the forest, create openings, and plant a diverse community of plants back in these areas. This important work also helps to ensure better water flow and storage over time into our wetlands, streams, and rivers, and recharges our aquifers when we encourage diverse habitats that benefits not only wildlife, but plants, salmon, and the people of the Nisqually Watershed. 

Washington Department of Fish and Wildlife (WDFW) would like to have reports of any observations of these Western Toads or other threatened or rare species. To do so, use the ‘At-Risk” wildlife observation form: WDFW Wildlife Observations (arcgis.com)

Western Toad Factoids: 

  • WDFW was very excited about the recent find. They confirmed this is the 5th known breeding population of Western Toads in Pierce County. 
  • Individual females produce approximately 12,000 eggs per clutch on average (estimated counts range 6,000 to 20,000).  
  • They spend most of their life in terrestrial habitats, such as prairies, forests, canyon grasslands and ponderosa pine-Oregon oak habitat. They only breed in waterbodies to reproduce, like wetlands, ponds, lakes, reservoir coves, and the still-water off-channel habitats of rivers, as well as river edges. 

Species Spotlight – Western Bumble Bee

Lindsie Lawson

Species Spotlight: Western Bumble Bee (Bombus occidentalis)

This month, we cast the Species Spotlight on the Western Bumble Bee!

While its coloring varies, it is commonly identified by a black abdomen and a tail that appears to be dipped in white.

Upon visiting one of our properties north of Ashford, Stewardship Manager Jake Pool found 14 different pollinators on one goldenrod patch in just 30 minutes of observation! Among these was the Western Bumble Bee.

The Western Bumble Bee is native to the west coast of the United States and Canada. What was once a common species across a vast region is now in decline and even considered quite rare.

As a generalist pollinator, the Western Bumble Bee is very important to the local ecosystem, pollinating a wide variety of flowering plants. It lives in small, annual colonies that depend on diverse flora, as well as logs, stumps, and abandoned nests throughout the nesting season. It prefers the cooler temperatures found in subalpine and montane areas.

Currently, the Washington Department of Fish and Wildlife has classified its sensitivity to climate change as Moderate-High, as shifts in temperature, precipitation, and snowpack impact its nesting and other practices.

Conservation Concerns

The Western Bumble Bee is currently designated as a Species of Greatest Conservation Need under the State Wildlife Action Plan, as well as a Priority Species under the WDFW Priority Habitat and Species Program. In a study conducted by the U.S. Geological Survey alongside bumble bee research groups, data showed a 93% decline in occupancy from 1998 to 2018. This trend of decline has continued, and recent surveys in Washington show a small number of remaining populations across the state. WDFW has requested that these be reported whenever seen.

NLT Protects Habitat

Much of our field work by partners, volunteers, and staff includes planting native plants such as Willows, Maples, Goldenrod and Pearly Everlasting, as well as invasive weed management across Nisqually Land Trust properties. By replenishing these plants which are especially popular among pollinators, we hope to support a healthy habitat for the Western Bumble Bee, along with many others.

Species Spotlight – Nisqually Chum Salmon

January Species Spotlight

Nisqually Chum Salmon (Oncorhynchus keta) 

By Heather Paladini

Each month, we will spotlight a species of fauna, flora, or fungi from within the Nisqually Watershed. Stay tuned to see what’s being spotted in the watershed each month!

This month, we cast the Species Spotlight on the Nisqually chum salmon. 

The Nisqually chum salmon run in the winter. They use the lower parts of prairie streams in the Nisqually River watershed for spawning, including both Muck and Yelm creeks. Muck Creek supports four species of salmonids, with chum being the most numerous of the anadromous fish in the creek. Muck Creek is also the most significant stream for Nisqually chum, as the largest proportion of these chum spawn here. Up to one-third of the entire Nisqually River chum run use Muck Creek.  

The Nisqually winter chum run is the latest-timed chum run in the Pacific Rim.  While other Puget Sound chum spawn in November, the Nisqually chum spawn in late December through January. Why do these salmon run so late? What makes these chum salmon different from others?  

Nisqually Chum: Unique Adaptations

These chum are thought to be genetically unique. By reacting to different environmental conditions over time, they have adapted to prairie streams including Muck Creek, and the hydrology of the river and its tributaries at this particular time of the year. 

A Pierce County report on the Muck Creek Basin suggests that the chum that use Muck Creek for spawning have been influenced by its intermittent stream flow conditions. As a result, they have timed their runs to coincide with passable stream flows which happen later in the season. Adapting to the unique stream flows of this creek, which favor late-arriving fish, is a phenomenon seen in other spawning fish populations elsewhere. 

This adaptation may give these chum an advantage over their fall counterparts. It enables them to avoid most of the winter floods responsible for displacing salmon eggs within the gravel or smothering them with silt. Additionally, this allows for faster incubation: the later they arrive, the warmer the water will be for the incubating eggs.  

Another advantageous attribute of the chum is that half of the adult chum in any given year returning to Muck and Yelm Creeks are 3 years old and the other half are 4 years old. This makes them more resilient to unusually calamitous stream flow years, because it would only affect half the population of a brood, with the other half returning a different year. 

Cultural Significance of Nisqually Chum

The late-timed chum are culturally significant to the Nisqually Tribe because they are the only fresh fish returning at a time when other salmon runs are over. Historically, the winter chum run was an entirely wild salmon run that could support a harvest. Unfortunately, the runs in recent years have been declining and are no longer large enough to support a fishing season.   

NLT Protects Nisqually Chum Salmon Habitat

The Nisqually Land Trust works to protect and steward important salmon habitat lands including the lower reach of Yelm Creek, an important habitat for the Nisqually chum. The photo and video shown here were taken at Yelm Creek on the Petersen Farm. NLT has a conservation easement at Petersen Farm and works closely with the Petersen family to conserve salmon habitat for this genetically unique species of salmon.  

Nisqually chum salmon in Yelm Creek

This chum was spawning in the lower Yelm Creek a couple of weeks ago, and he gave our ED Jeanette a close-up chance to meet him. Notice his beautiful purple-red vertical markings and his well-developed teeth. These canine-like teeth may be what gave the chum their common alias dog salmon.  Photo credit: Jeanette Dorner

Settling Into The Volunteer Coordinator Groove – Emily Simroth

Kim Bredensteiner

My name is Emily, and I serve as the Habitat Stewardship AmeriCorps Member with the Nisqually Land Trust. My responsibilities include leading habitat restoration volunteer work parties once or twice a week and coordinating the site steward program, through which volunteers “adopt” a site to periodically monitor for human impacts, invasive plants, and other issues. I also spend over half my time in the field, serving with other staff and my fellow AmeriCorps member on environmental stewardship projects across the nearly 6,000 acres that Nisqually Land Trust owns.

In the past, I’ve volunteered for local community organizations many times, from attending one-off events at an animal shelter to helping out every week at a pollinator garden. I had great experiences with other volunteer coordinators who were enthusiastic, knowledgeable, and great at making me feel part of the group. When I started this position, I was excited to step into that role, to be the one recruiting volunteers and welcoming them into the Land Trust community, to be the one sharing what I know about the land we work on and the importance of protecting it. I hoped I would enjoy this part of my service, but I was nervous, too—I had never served as a volunteer coordinator before.

These past few months, my hope was validated. I discovered that volunteer coordination is something I would be happy to continue doing beyond my term in AmeriCorps. Each week I advertise events, recruit volunteers, and lead work parties—welcoming volunteers, introducing them to the task of the day, checking in and answering questions, and of course, handing out snacks.

Over these past few months, the volunteers I coordinate have contributed over five hundred hours of their time. They planted over two thousand trees and shrubs and removed dozens of garbage bags worth of invasive species and old plant protector tubes. The volunteers have a shared passion for the environment that is genuinely inspiring to be around, and each individual brings their own knowledge and experiences to the work we’re doing.

This November in particular, groups of volunteers came out to a field along the Nisqually River multiple days a week to plant native trees, shrubs, and wildflowers. It’s great to see familiar faces each time—from folks who’d been coming to work parties for years, to those who joined for planting this year and returned week after week. I love chatting with the volunteers I already know, hearing about what’s new in their lives as we work and learning from the expertise of those who have been doing this work longer than I have. I have a tremendous respect for those who choose to give their time, week after week, on rainy days and freezing ones, to help make the natural environment a bit better, tree by tree.

At the same time, a new face is always exciting. I love getting to know folks who haven’t worked with the Land Trust before, learning what motivated them to come out on a Wednesday or Saturday morning, and in turn, sharing what the Nisqually Land Trust does and explaining how the forest we’re restoring in that field along the shore will be important for the salmon, who need a shaded river with woody debris from fallen trees. I always enjoy taking new volunteers (and some returning ones!) down to the Nisqually after we finish planting for the day to share more about the river—from the needs of the salmon who live in it, to its dramatic erosion of the bank we’re standing on.

The accomplishments of all our volunteers are incredibly motivating. It’s so satisfying to look back at the rows and rows of plants that are in the ground at the end of the work party and announce that this morning, we’ve planted hundreds.

As one of four people on the field stewardship team at the Land Trust, it’s easy to see that we couldn’t tackle projects like that November planting without all the volunteers who chose to pitch in. I’m so glad I’ve had the opportunity to get to know these folks through my AmeriCorps position, and I look forward to many successful Wednesday and Saturday morning work parties in 2023, as we begin our next planting projects.
