International Bat Night Included Arden's Story, A Local Tale by Kathy

8/29/2021

More than 60 bat experts from 40 countries were showcased on Facebook Live for International Bat Night hosted by Nils Bouillard, a Bat Conservationist from Europe, from 8-27-21 at 10 pm PDT to 8-28-21 at 2 pm. We are very proud and honored that our very own JoEllen Arnold of Sacramento, California, was one of the participants who gave a fascinating illustrated talk about a Hoary Bat named Arden.

JoEllen has had a passion for bats for many years. She loves to travel around the world to see and photograph some of the more than 1400 species of bats and to share what she learns. About 10 years ago, she started helping with the rescue and rehabilitation of our local native bats with NorCal Bats.

For the International Bat Night event, she told the story of "Arden", a Hoary Bat who came into care with NorCal Bats in February. Arden was found on a gravel driveway in a residential neighborhood off Arden Way. She looked fine but could not fly. Her right wrist was swollen, and over time, Arden’s wing membranes deteriorated horribly. It is thought that she was suffering from Wing Wasting Syndrome which is caused by a bacteria in the soil. After being treated with antibiotics, the deterioration was stopped, but Arden will probably never be able to fly well enough to be released. Toward the end of April however, it became clear that she was pregnant!

Arden gave birth to a male and a female pup in early May, right on schedule for a Hoary Bat. Sadly, the female pup did not survive her first night, but the male has grown up to be a beautiful Hoary Bat. He will be going to a flight cage for flight practice and it is hoped that he will be released shortly thereafter.

Thank you JoEllen for all you do in rescuing and caring for our local bat population! Go to NorCalBats.org to learn more about how you can help our local bats. Donations and volunteers are always needed!

Note from webmaster: Many thanks to Kathy and JoEllen for collaborating on this important story. Many of you will remember the inspiring and very popular evening bat conservation programs JoEllen has hosted for FORB over the years. We can't wait until that becomes possible again. Meanwhile, you can listen to an interview, "Getting Batty With JoEllen" she did during this local radio show episode (starts at min 6:28).

Tide Study (and tidy work) at SLP by Mark

8/13/2021

Jax might be measuring tidal movement...

(Check out the updated video at the bottom showing ongoing cleanup work along the river 8/29/21)

After many years of visiting Sutter’s Landing, I could never figure out why the river was always at different levels. I always wished I could figure out when they were releasing water so I could better pickup trash. Then one day a couple months ago, while paddling with my friend Tom, I became aware that there was a tide. I was shocked how simple it was. I couldn’t believe I never realized it before. Then I found out that many of us didn't know about our river tides, so I wanted to share.

My study is located on the large pipe, just past the downstream fence at SLP. Past the rope swing.

This month’s high tide, which happens twice a day, varies between 1.9’ and 3.3’. Low tide varies from -0.1’ to 1’. The Sacramento tide chart is measured at the Sacramento River in Old Town. SLP’s tide is different.

According to the Sacramento tide chart, on Aug. 6 at 2:58pm there was a 0’ low tide. At 2:58pm I set my yardstick at 1”. By 4:20, the water had dropped 2 more inches. Hoping that was low tide, I readjusted my yardstick down to 0. The next day the chart said there was a 3.2’ high tide at 5:57am. . I was there at 6:40am and measured a 28” tide, the stick was dry above telling me we were at high tide. On Aug. 11, I took a picture that showed watermarks on the yardstick that showed several tide levels.

I don’t know how scientific this is but hopefully you find it interesting. I have been obsessed with the river recently and have learned so much about it’s ecology and politics from some masters of the river. Thank you.
.
This year I decided to take my vacation at Sutter’s Landing. It has been a fantastic trip. I have explored much of the lower river and spent half the days, with my dog (Jax), cleaning between miles 3 and 4 across from SLP. It is beautiful over there, much cleaner than I expected.

In the last 2 months, I have cleaned dozens of abandoned camps and thousands of pounds of trash from right next to or in the river. FOSL and county maintenance crews have been very supportive.

It has been wonderful meeting so many dedicated people in love with the Parkway.

webmaster note:
Mark has raised the bar greatly this year with frequent nautical outings to float trash back into containers. Who says a person can't make a difference!
A great place to check on the latest river flows and temperatures for the lower American River is the Water Forum website.

Bushy Lake Burns Again...

6/13/2021

0 Comments

Ground level view of the smoke plume over Bushy Lake June 6th 2021

Bushy Lake is a designated Nature Study Area in the lower American River Parkway. This site is adjacent to CalExpo and directly upstream from Sutter's Landing Park. In recent years an ongoing monitoring project has been underway lead by Dr. Michelle Stevens and her CSUS students. Dr. Stevens recently was awarded a state grant from the American River Conservancy to develop a long term restoration plan. Unfortunately, her established restoration site burned up in this latest fire along with well over 100 acres of important habitat for sensitive species including the Western Pond turtle, Swainson's hawk and more. This habitat is shared with wildlife frequently seen at Sutter's Landing Park and the Lower American River Parkway. Research and restoration will work will continue from the ashes.

There have been many fires already this year in the lower American River Parkway. This fire at Bushy Lake has been one of the worst so far. The latest fire burned for several days and has raised questions about fire management in the Parkway and best practices when responding in a Nature Study Area. A shared photo/video album is available with much more on the breadth and degree of impacts of the fire.

Looking south across Bushy Lake towards the American River from the CalExpo levee.

June 8, 2021 To: Whom It May Concern
From: SUBJECT: June 6 Wildfire at Bushy Lake

Dr. Michelle Stevens, Bushy Lake Eco-Cultural Restoration Principal Investigator

On Sunday June 6, a team of scientists and student research assistants left Bushy Lake at 1:00 pm after conducting turtle catch-and-release research and nest surveys. At approximately 2:00 pm, a wildfire started at a human encampment on the east side of Bushy Lake. The fire burned to the eastern shore of Bushy Lake, burning all vegetation in its path. There was no discernible effort by fire crews to stop the progress of the “slow moving” fire toward the Bushy Lake Restoration Project (see Figure 1 and 2).

Sacramento State faculty and students have been conducting experimental plantings of fire resilient and culturally important native vegetation for the past five years (see Figure3). Over 600 students and community volunteers have been involved in planting, weeding, conducting experiments, and watering plants at the site. The wildfire destroyed the entire restoration effort. Previous fires occurred in 2014 (entirely destroyed the site, and when we began restoration work through the Earth Stewardship Initiative). Another fire occurred in 2016 and was stopped outside our experimental area on the south side of Bushy Lake.

What was the impact of this fire? The northeast side was burned from the Cal Expo levee to the water, the east side burned through our restoration project to the water, and I don’t yet know how much of the south side burned (see Figure 4 and 5). Turtles are nesting right now, with the females moving from the water to the upland to lay their eggs (see Figure 6). Besides destroying approximately six acres of planted native vegetation, we have recorded nesting western pond turtles, over 160 species of birds, resident deer and coyote and other wildlife species, Valley Elderberry Longhorn Beetle habitat and elderberry savanna, and over 50 species of butterflies and other pollinators (see Figure 7 impact on wildlife).

We will have an internal team meeting of scientists engaged on the project to determine our next steps. We will incorporate the “disturbance” into our study in order to make recommendations to inform our conceptual restoration plan, specifically in regards to fire resiliency. We have a number of questions to incorporate into our study after we have time to determine what is left and in what condition.

1) As soon as it is safe and the fire is out, we will continue nesting and population surveys on western pond turtles and non-native turtles;
a. Observation: did beaver presence and “beave way” construction on the site increase fire resilience?
b. Observation: will turtles use the burned areas for nesting sites? Will we find burned turtle nests in the burned areas?
c. Observation; will turtles depend more heavily on unburned areas of the site?
2) We will monitor shifts in avian use of the site, determine bird use and nesting success, aquatic
biology and water quality post fire;
3) We will monitor survival and revegetation of native plant species to determine fire resiliency;
4) When the rains come, we will replant the reference on-site restoration project with donations
and assistance from the stakeholder community;

Finally, there have been three major fires in the Bushy Lake area since 2014. These fires are created by continued anthropogenic activity. Wildfires endanger human health and safety in a beloved recreational and education area on the lower American River Parkway. These fires undermine natural resource management, conservation, and restoration efforts, and pose a threat to Cal Expo and a major transmission corridor. What plans are in place to remediate these anthropogenic threats?
I did not observe any attempt by the fire department to protect the natural resources at Bushy Lake. Why was no line dug to protect the restoration project from what is described as a “slow moving wildfire from the east”? Are natural resources designated as a state nature preserve or restoration site a priority to be protected when wildfires erupt? Is it time to create priorities for natural resources along the lower American River parkway to protect natural resources from wildfire?
Hundreds of thousands of dollars of taxpayer funding, hundreds of hours of faculty, student and community elbow grease, and a great deal of love from many stakeholders on the lower American River have gone into the Bushy Lake Restoration Site. We plan to continue our study to the best of our ability, and make use of this wildfire “stressor” to continue our research.
However, as we continue our work, I want to know there is some kind of policy safeguard against these anthropogenic wildfires and their constant threat to Bushy Lake and other areas along the American River.

Spring & Early Summer at Sutters Landing Park by Robert

5/31/2021

0 Comments

Hello to all,

This spring we saw and welcomed the early return of two Swainson's Hawk (SWHA) couples to Sutters Landing Park and right away they started nest building, which is an ongoing process! As you can see below, one couple built in a Black Locus tree while it still had fragrant spring flowers on it. That’s the first nest I’ve ever see built in this species of tree and also this far down river!
The other couple choose to build in a tall riverside Cottonwood tree, as all other Swainson's Hawks have.

A large patch of Native Wild Roses bloom each spring! They line the left side of the canoe trail down to where the sand begins.

We think this is a Sweat Bee.

This is the Yellow-face Bumble Bee, bumbus veses en kii. Wild Roses are it’s favorite!

Honey Bees are also attracted to the Wild Rose.

A lovely sunset on the river.

Cottonwood seeds fill the air.

Notice the abundance of Horsetai l Plants.

This SWHA has a catch! It caught as the mower cut the dry grass on the mound.

This Common Merganser mom's chicks have already learned to help her hunt for small fish!

They look as if they are running on the water!

She has a large clutch of eight chicks!

Pacific Gopher Snakes mating on the river banks are native to the western coast of North America. They range in size from 5 to 7 feet long. Their eggs are laid from June to August and will hatch in 2 to 2.5 months and the clutch is from 12 to 14 eggs. They are nonvenomous.

Look closely and you’ll see this is a Nursing Coyote Mom on top of the mound where her young pups have been seen this summer.

iNaturalist is a citizen science tool available on smartphones, tablets and computers. It's managed by experts at the California Academy of Science. Easy to use, it can capture an observation you make and share it with others to help better understand the amazing species and habitats around us. You don't have to know what you have seen as online experts will help with identifications and the app provides much information about species characteristics and range. iNaturalist can be used for all species from insects, plants, fish, birds, reptiles, mammals, trees, and more. The app is free to download and membership with iNaturalist is also free. If you want to take a closer look at species that have been recorded at SLP using iNaturalist, check out this link. More recently there were several Osprey iNaturalist sightings in flight over SLP. What will you spot and share on your next outing?

Similar information is available for the rest of the Parkway as well as most other locations around the globe. There are also special projects and other community activities and forums where you can share and learn more about your favorite groups of species. There are a number of other great apps that can expand your enjoyment and experience with nature at SLP, other areas of the Parkway and wherever else you may go.

Unfortunately, not all of those experiences may be positive but that is important to document too. See below.

Unfortunately not all observations in the Parkway are beneficial to nature or recreation (taken 5/16/21 about 5 PM)

Likely another human caused fire in lower Am River Parkway burning grassland and upland habitat.

Woodlake area of the Parkway is across the American River from SLP and site of many recent human caused fires like yesterday

Strong winds blew smoke and fire rapidly northward before fire crews could arrive.

On the way home after another great bike outing in the Parkway yesterday, I encountered a rapidly spreading fire in an area of Woodlake that has been burned many times in recent years. Most of these fires are human caused. The fire yesterday occurred in strong winds and spread rapidly before fire crews could arrive. It turned day into night and was impossible to see the ground as I made my way through the burning area before being cut off. Unfortunately many more areas of the lower Parkway have already been burned this year and that number and impact will greatly increase before the rains return. Several habitat damaging fires in the Discovery Park area are very visible from the bike trail now.

New Swainson's Hawk Nests at SLP by Robert

4/25/2021

4 Comments

Hello to All,

This April 13, 2021 was the first time nesting Swainson's hawk pairs have been seen and recorded at SLP since April 3, 2018. This raptor is a California Threatened species that has declined due to loss of nesting and foraging habitat.

Both nests are further downriver than we've ever seen. One nest is in a Black Locus tree, another first for me, and the other is in a Cottonwood tree, the type of tree all other Swainson's hawk pairs have used here in the past.

We are delighted to see Swainson's hawks return and wish them success!

Good to see colorful Damselflies emerging

This Swainson's hawk did not take a drink of water, that’s a sight I’ve never seen, but it might have be soaking something in its left talon?

Flying off to its nest

Maybe a dragonfly in larval stage?

Further up river in a Cottonwood, nesting materials continue to be brought in.

Many little fish can be seen along the rivers edge near its sandy shore. Perhaps salmon fry?

Lady bug and Box Elder bug.

Fly on and on and on!

Nesting Time! by Robert

If you’re a bird just arriving now you’re almost late for finding or building a nest along the river banks at SLP and some species have chicks already! It’s been a warm sunny spring and many birds are fortunate to find older trees that already have nest holes, so come up and take a hike to see them and wish them well! It’s amazing to know how many insects are eaten, (especially mosquitos) by small birds such as the Tree Swallow below.

Tree Swallow

House Wren

Tree swallow in nest

Rough winged swallow

This broad winged, short tailed Northern Rough-winged Swallow, is not so common here but we’ve seen them nest in holes in sandbanks and crevices of walls along the river. They visit us from February through mid September.

This Canada Goose couple already has six chicks and dad watched me closely to make sure
I was not going to interfere as mom lead then uphill to nibble on grass.

Fluffy now but feathers will come soon.

This Tree Swallow was busy gathering and filling their nest with a variety of grass and plant fibers.

Owl's Clover

It’s wonderful to see such a variety of colors, sizes and shapes.

Tidy Tips

You can’t miss all the colorful wildflowers that line much of the bike trail.

Enjoy your visit!

Hi Friends,

With the warm springlike weather we’ve been enjoying, I’m seeing some courting and nests are getting spruced up. With the exception of one cutie, the birds featured in these images are a Northern Harrier Hawk couple. They are a welcome sight because they are ground nesters and if they build a nest here or close by, we might see them flying over the mound (which is where these photos were taken) or somewhere nearby, all summer!

The cutie I mentioned is the Goldfinch. Sometimes they’re hard to see in dense tree & shrub thickets, but their songs make it worth pausing, listening a nd enjoying.

This is the male Northern Harrier, often called the Grey Ghost! □

When hunting, they fly close to the ground like owls so they can also hear their prey, which are usually rodents.

Notice the white “rump patch”. It's the distinct mark of these hawks

Just made a catch!

Looks like she caught a mouse for lunch!

We are glad the grass is allowed to grow all summer and not mowed, as it was long ago, so ground nesters like the Meadow Lark and Northern Harrier can safely rear their young. Now, thanks to our knowledgeable SLP maintenance crew, the grass is only cut after it grows tall, turns brown and becomes a fire hazard.

Photos from Sea Lion eating fish at Discovery Park by Robert

December 30th, the end of the year and I couldn’t remembering seeing one of the largest animals that I most always see in the lowers stretch of the American River, especially during the Salmon run, the Big Sea Lions!

So I thought I’d ride down to Discovery Park where you can often see S L at the confluence of the American & Sacramento Rivers, where spawning fish like Salmon often check things out to determine which way should I go to get back to my spawning grounds, or hatchery.

Then I heard a familiar loud splashing sound, along with Gulls circling close above, that let me know not only was a S L close by, but it had made a catch and was in the process of ripping apart the tough skin and scales of its catch to get to the meat of it all!

I felt so fortunate! Yahu!

Beautiful fall scene along the American River at SLP. Photo by JoEllen Arnold

FORB has been a part of this important survey effort for over 5 years now as "Team Otter". This year it was necessary to take extra precautions but several members of the team (JoEllen and Dale) were able to spend a few hours individually counting birds and other wildlife again.

The combined count has been entered into eBird where it is added to other count areas and data for the American River Parkway. This citizen science effort is helpful with trends and species abundance. This year it felt like recent habitat impacts at SLP might have contributed to lower numbers of songbirds and the overall species count. Here's the summary from Team Otter:

2020 ARNHA Wildlife Count Checklist Team Otter
