Badger Hole Hollow — Outdoor Classroom installs a Wildlife Habitat

May 012015

Badger Hole Hollow is a cleanup project turned Wildlife Habitat Installation. This project is an Outdoor Classroom project: Orchard View School; Sunny Galbraith, teacher, and 7 of her Biology students. Location: Laguna Environmental Center. Date of classroom project: April 15th, 2015.

The Laguna de Santa Rosa Foundation operates the Laguna Environmental Center, or LEC, on Stone Farm, at 900 Sanford Road, Santa Rosa, California, 95401. This wildlife habitat installation borders the LEC’s (Laguna Environmental Center’s) Native Plant Nursery, which is used for the Foundation’s Conservation Program.

About 2 years ago, on October 3, 2013, a massive valley oak fell in Doyle Park, Santa Rosa. The City of Santa Rosa had sections of the tree hauled off to one of its wood “graveyards”. The Laguna Foundation coaxed Stone Horse‘s farmer, Stuart Schroeder, to use his implement carrier to bring sections of the huge Doyle Park valley oak to the Laguna Foundation, the purpose being to foster landscape rehabilitation to the Laguna Environmental Center’s fairly recent construction zone around Heron Hall.

“Just a little to the left and back a bit.” Doyle Park Heritage (valley) Oak section is added to the habitat landscaping of the LEC. Note the implement carrier, with its 4-chain hoist — a flywheel at the head of the metal frame’s roof turns pipes that winds those chains around the pipes. The chains shorten thereby lifting the load. Great way to lift a tree! And move it!

2013.

2015. These oak sections, although they will ultimately “return to the earth”, could look more naturally placed in the landscape. They will be repositioned to hide the human-made chainsaw cuts. And in doing so a wildlife habitat will be created.

Close-up of BEFORE. Two oak log sections with their chainsaw cuts facing each other.

A lot to prep before the students arrive. The larger section will be partially buried — the chainsaw cut will sit in a hole and the shredded, more-naturally broken end will twist skyward. One end will create den structure for subterranean animals and the other will provide perch-above-the-grasses for climbing animals and birds. Woodchip mulch is dumped against Trunk (the larger section) 2 weeks before installation date to wick water to the adobe soil below. Softening the soil with moisture will make the digging soooo much easier!

Woodchip mulch is piled up against Trunk (larger section) and watered to moisten the adobe soil 2 weeks prior to digging.

One day before installation date. Staff and an intern discuss pulling weeds. One staffer has a weed by the throat. This native plant landscape will some day be a native plant meadow; till then, weeding is an essential job. Note the soil bins in queue next to the oak logs — they will store soil as the hole for Trunk is dug. Bin 1 = top soil; Bin 2 = layer under the topsoil; Bin 3 = less rich sol, adobe clay; Bin 4 = heavy adobe clay. The bins were labeled as dug and stored to allow the correct bin/soil layer to be returned to the habitat installation at the right time. Preserving the soil layers helps disrupt the soil ingredients less, including critters and soil microbes. Nutrients and critters that were living in the topsoil remain in the topsoil. The same is true for the other soil layers.

A note labels Bin 3 to sequence when its soil will return to the installation.

The spade head marks the spot — we will bury our treasure (Trunk) here. The smaller oak tree section, which has been subsequently named “Crocodile”, has been moved out of the way. A cardboard barricade has been temporarily installed to throw dug soil onto; a pile will be created close by to be able to cover over Trunk/hole once Trunk is slid into position, that is, dropped into the hole.

Digging so that Trunk can drop into a hole. The soil pile will return over Trunk, then planted.

Trunk is coaxed via truck chain into its 4-foot hole rest.

Almost there — time to remove the lower chain bolt. Once the lower bolt was removed, the Trunk was edged vertically into the hole from the chain looped around Trunk’s “top” end.

The next morning — installation day for Badger Hole Hollow! The digging bar perimeter will help the students walk carefully around the native plants living alongside Badger Hole Hollow, or “BHH”. Trunk is far enough in the ground it will stay put, minimizing any danger issue. The smaller oak section, Crocodile, will be positioned by today’s Biology class students.

Julia, a student donating her time at the LEC, transplants native plants, like the California poppy (Eschscholzia californica) shown above, to a temporary mound of moist woodchips. The collected plants will be saved from being trampled during the installation and then will be replaced on or alongside Badger Hole Hollow as a finishing touch. If 1 out of 3 or 4 survive the transplant, at least there will be one more native plant to jumpstart the installation.

Orchard View students are on site. Red and blue irrigation flags were used to create easily visible walkways between the established (wanted) native plants.

Crocodile wrestling — students position Crocodile into a position that will maximize the wood hulk’s ground surface coverage (for animal shelter) and its landscaping beauty.

Students break up a stick pile 1) to get rid of the pile of sticks from the compost pile, and 2) to provide organic debris under the habitat installation’s soil planting. Microbes to crawly critters to critters that eat those lower trophic animals will call the small buried stick pile home, habitat.

A student breaks up sticks, then uses his body weight to compress the broken stick pile up against Trunk and Crocodile.

Soil is backfilled (background) and woodchips are mixed into the habitat to prepare for plantings.

Juncus, or California gold rush (Juncus patens), is planted in between and at the base of Trunk and Crocodile. The juncus, which love moisture, will be on and downslope of the soil/woodchip pile between the 2 oak tree sections.

Field sedge (Carex praegegracillus) plugs are planted in the surrounding area of BHH. –Per Wikipedia, “ [Field sedge] tolerates disturbed habitat such as roadsides and thrives in alkaline substrates.” In other words, field sedge is a good choice for our native plant restoration, and subsequent wildlife habitat creation, of this graded soil next to LEC’s road.

Fields sedge and juncus are planted on Badger Hole Hollow’s hill.

Badger Hole Hollow gets water. This outdoor classroom rocks!

Badger Hole Hollow wildlife habitat has been installed AND field sedge plugs have been planted up to the road’s edge.

A jack rabbit leaps (center of photo) above the landscape’s sedges and grasses as the project is cleaned up.

Badger Hole Hollow will rest now and enjoy the sunset.

Close-up of AFTER. All in all, Trunk and Crocodile have had a great day.

Will a badger come to live under or near Badger Hole Hollow? Perhaps, perhaps not, but in the meantime, the critters of the landscape have another option in the terraine.

The students of Orchard View School, teacher Sunny Galbraith, and Cordy and David and I had fun at this outdoor classroom Biology project. A thank you also to the Laguna Foundation’s staff, especially Wendy Trowbridge, Director of Restoration and Conservation Science Programs, and Brent Reed, Restoration Projects Supervisor. Thanks for the plants, Brent. Cool project!

Enjoy your wildlife habitat creations. Habitat it!

Cricket Compost Corral is a wildlife habitat installation that was installed October 2014 at the Laguna Environmental Center. This post is about moving a garden resource (debris) pile to Cricket Compost Corral. The new compost will help jumpstart the compost pile and the wildlife habitat features of the pile. The new compost will help raise the soil level of the compost so that the compost will drain better, stay warmer, and work more efficiently. Also, the new compost resources will come with a rich biota of fungi, soil microbes, crawly critters, and perhaps animals of higher trophic levels.

The Laguna de Santa Rosa Foundation, operates the Laguna Environmental Center, on Stone Farm, at 900 Sanford Road, Santa Rosa, California, 95401. This wildlife habitat installation borders the LEC’s (Laguna Environmental Center’s) Native Plant Nursery, which is used for the Foundation’s Restoration Program.

“Cricket Compost Corral Gets A Habitat Blanket” is an outdoor classroom project — Science is just the beginning! The students of Orchard View School, substitute teacher Alison, and I had fun at this outdoor classroom Biology project. Teacher Sunny Galbraith worked logistics before installation day.

Before the students arrive — fenceline garden resource pile:

Foreground = Veggie Garden at the LEC. The resource debris pile to be moved is in the background, straight back off the garden’s corner, next to the fence, left of the propane tank.

Winter rains have greened the grass around the resource pile.

Everyone grab a tool. Let’s move this pile!

“Rusty” will help us move the resource pile across the LEC grounds quickly, saving a lot of wheelbarrow loads.

Gathering organic debris (horse manure and fallen poplar branches) to add to Cricket Compost Corral.

Using the gathered manure/branches to build up a side of CCC.

Farmer Stuart Schroeder, of Stone Farm, lends a tractor to add a layer of wood chips for the students to spread.

Logs are used to frame the new resources added to CCC. The wood frame will help keep the new higher soil level intact, wick water to the Santa Barbara sedge to be planted, and provide habitat for critters.

Moving the resource pile:

Students haul off the resource pile to the truck trailer.

A Pacific Tree Frog (Pseudacris regilla), green phase, hides in the resource pile.

Keep it Science — we listed all the critters we saw. The resource pile is a critter mystery pile.

Adding the resource pile to Cricket Compost Corral:

Wood chips are spread to make a rich base for the resource pile on Cricket Compost Corral.

Foreground, a student plants Santa Barbara sedge, a native, drought-tolerant plant that will hold the compost’s hill in place. Far right (back), students install driftwood to complete the frame of CCC.

Unloading Rusty the Trailer. About this time during unloading, a western fence lizard was found in the trailer and introduced into Cricket Compost Corral. You have a new home!

One garden’s debris is another garden’s treasure.

Securing the end of CCC’s frame with driftwood held in place by palm tree frond wedges.

Finishing touches on CCC gets a habitat blanket:

The veggie garden resource pile now sits on top of Cricket Compost Corral.

Tree limbs are staked into place to terrace plant Santa Barbara sedge along CCC’s front edge. The compost gets a lot of fuel from keeping the Nursery’s concrete swept.

More stakes.

Cleaning tools before our class is finished. Terrace planting of Santa Barbara sedge to keep the compost’s soil level from eroding. Ultimately, the wood will rot away but the sedge mound will hold the soil in place. The sedge will also provide habitat for the compost’s critters.

Garter Snake Ravine — a Wildlife Habitat Installation

1- Residential Habitats -- Critters and Their Homes, 6-Outdoor Classroom, Blog Comments Off

Jan 282015

Students pull up Garter Snake Ravine’s barn owl perch using a block-and-tackle.

Garter Snake Ravine is a wildlife habitat installation that incorporates a deep hole cut into adobe soil, a water reservoir, a large-branches heap (BIG stick pile), a Fungus DreamWorld, and a Science Experiment.

As mentioned in Spore Lore’s post, Prep for Garter Snake Ravine, 1-3-2015, the adobe hole, AKA “Ravine”, was left full of water to soften the hardpan adobe soil in the bottom of the hole. Sure enough, a week later, we were able to dig the hole another foot deeper — that much more space/capacity for the new habitat installation. The deeper hole will also give the owl perch more vertical stability; the upside down poplar tree will be buried deeper.

A long-handled posthole digger at the ready in Garter Snake Ravine after a week of soaking the hole with water.

The dug-out adobe soil was used to raise the compost’s ground level to help keep the compost out of winter’s wet. Garter Snake Ravine is two doors down from Compost Cricket Corral; Log Pile Apartments is between them. So to review, in the photo above, the water is overflowing Garter Snake Ravine, flowing under Log Pile Apartments, and moistening the raised banks of Compost Cricket Corral BUT not saturating the compost pile because of the now raised soil level of the compost piles.

A tree has fallen! No one was there to hear it but the crushed fence leaves a reminder. The poplar tree split at its crown with the snapped-off trunk landing into the adjacent horse corral. Problem: tree in corral. Solution: we just found ourselves an owl perch.

A 16-foot section of this poplar tree trunk will become an owl perch in Garter Snake Ravine wildlife habitat.

Because the tree is a poplar, we want to use it in a way that it will not sprout, thrive, and eventually shade the compost piles which are west (shady side) of Garter Snake Ravine. Poplar (Populus) trees are similar to willow trees in that they are both riparian species widely used for stream/watershed restoration. Both Poplar and willow have high levels of rooting hormone. And that’s a problem here — the Ravine habitat will be a water-/moisture-filled vase, like that for table flowers, during the coming wet months. Solution: “plant”, or install, the poplar tree upside down to prevent the rooting process. And don’t forget the trunk stump. This hulk of poplar wood will add to the habitat’s hugelkultur mass. Also, heavy, bulky pieces of wood like this one and others will help stabilize the owl perch, keep it from falling. Note how a staircase of skids was used to roll the stump into the bed trunk. Great to have a helping hand.

The poplar trunk stump waits on the sidelines until the owl perch is placed into the Ravine.

Our initial desire was to raise an owl perch high in the sky to encourage barn owls to hunt and feed at the compost pile. A perch that the barn owls that live on Stone Farm can use. That pair of barn owls (Tyto alba) can sometimes be seen in the palm trees below the Office’s front porch. Hoo called in Rodent Management?

IPM, a Permaculture term, stands for Integrated Pest Management. Rodents can be pests around a farm and Stone Farm is no exception. IPM is a way to handle one of Nature’s jobs by Nature. Traditionally, by introducing, a cure animal. Problems arise when the cure-all species becomes a problem — no other species is well suited to control the alien plant or animal. Such is part of the reason that Native Plants and IPM are considered solutions to removing pests ecologically. Palm fronds are not accepted in the local Resource Center, which makes soil additives from the garden debris (resource!) brought to it. But the fronds will be an asset in the hugelkultur — critters will seek the nooks and crannies between the slowly decomposing fronds.

A bird cam is installed — the camera will be trained on the perch to view owls hunting and eating their meals.

Students create a small retaining wall made from stones and heavy clay removed from the Ravine’s hole. This berm will direct runoff water under the adjacent wildlife habitat installation.

The poplar owl perch is here! Students walk the perch up the woodchip pile to gain height advantage for installing the perch into Ravine’s hole.

Here comes the perch, heading for Ravine’s hole. Note the thinner tree limbs in the foreground; the tree section is being flipped upside down.

The poplar tree section’s thinner branches are tied together to better fit the upside down tree into the Ravine. Note the green rope crossing back and forth — the block and tackle is being threaded for pulling the tree vertical.

Students, on top of the woodchip pile, wait for the signal to assist the block-and-tackle’s raising of the owl perch.

Signaling to the rope puller, “Pull in the slack, batten down the hatches.”

“Pull!”, and up the perch goes with a little help from the top of the woodchip pile. Two safety lines were used in case the perch was accidently pulled past vertical. Note the safety line from the right-most student (right of the woodchip pile). The left-sided safety line is being held by a student standing behind and to the left of the woodchip pile.

The owl perch is edged into place. The poplar tree section has been up-ended.

Students stuff driftwood logs, the poplar stump, palm fronds, and smaller poplar braches (upside down) around the perch to stabilize it. Plenty for all hands to do now; we want to vertically secure the perch and remove the block-and-tackle lines and safety ropes.

Safety check! Lookin’ good; keep packing the hole around the perch.

Still more materials to pack around the perch as it approaches standing on its own, without stabilizing lines.

A breather while the owl perch is finalized. This outdoor classroom rocks!

Students are busy planting Santa Barbara sedge (Carex barbarae), programming the bird cam, and packing the Ravine.

Garter Snake Ravine wildlife habitat installation is completed. Note that the habitat has three major elements: a deep moist adobe hole that will fill to a small pond during the rains, a pile of branches and sticks, and an owl perch. That’s a lot of nooks and crannies for critters to hunt, hide, cool-down, and LIVE! in. First will come the wood-eating fungi and decomposer microbes, then higher trophic critters, then perhaps a mammal (an even higher trophic animal), like a skunk or a possum, that wants to reign over the habitat.

Garter Snake Ravine waits for a perching barn owl throughout the dark night.

Thank you for the wonderful pictures, Jenna.

Enjoy your wildlife habitat creations. Habitat it!
