Snowy Tree Blocks Buckeye Greenway

Downed Tree on Buckeye Trail in East Raleigh Blocks Snowy Greenway

High winds on top of rains toppled quite a few trees in the area, including this pair of medium specimens lying across the Buckeye Trail greenway at the bottom of Suicide Hill, as it was labeled by the cross country runners who used the greenway before its recent upgrade.  Lowered grade, I should say, since the cruelest, steepest stretch was lengthened and terraced to bring this oldest section of greenway into national codes.  Suicide Hill climbs a rugged quartz and sandstone outcrop that forms the Rocky Overhang, one of the seminal pillars of this blog, as it represents my favorite Crabtree hangout.

Raleigh Nature’s  ”scoop” on this downed tree is wonderfully fitting as I get back to basics after a bit of hiatus. Enamored of the Ken Burns series, engulfed by teaching responsibilities, and constantly lured by my current intellectual fling, Ray Johnson/Black Mountain/mail art, I have wintered in the blog a bit, but could not resist the lovely, harmless 3 inch fluff that ended on a Saturday morning.  So I took off for my favorite sight-seeing greenway, Buckeye Trail from Milburnie Road. At the edge of Rollingwood, Crabtree has carved out a tall bluff (at least for this part of Raleigh) and under this 40 foot hump the creek has gouged a fishing hole complete with overhanging boulder shelves from which to cast.  Drowning worms  and hauling up the occasional catfish or bream at the Rocky Overhang is a family tradition for me as child and parent.  Heck, I took dates there, I loved the place so much. I was slightly horrified the day soon after Hurricane Floyd came through to see that a very large sycamore tree across the creek had fallen directly onto the Rocky Overhang, and for several years it was too tangled to get down there.  The kids and I mourned but also learned some valuable lessons about how Crabtree changes over time.  Now that tree has finally eased its way mostly into the fishing hole (after forming a hideous litter trap for more than a year on the way in) and the boulders have cleared somewhat.  In the spring, we’ll take a look, but for now here are more snowy scenes from Buckeye Trail, a gall tale, and a link to the photo album from my snow walk.

 

The baby beeches we have admired before looked nice mixed into the snowy pines.  Below is the scene at the beginning of Buckeye, where Longview Branch parallels Milburnie as it slides into Crabtree.

 

Below is a  ditched brook that brings water from the slopes of Rollingwood under the greenway and into Longview Branch just before it reaches the creek.

Just off  Milburnie is the old landfill that now forms a rich meadow, a favorite browsing place of the numerous deer living in Crabtree’s floodplains in East Raleigh. 

Below are some deer and coon tracks in the February snow.

The stump of a large oak I miss very much looked just as sad in the beautiful snow.  This tree had the largest gall I ever saw – a triple-grapefruit sized lump that housed the larvae of box elder beetles.  Greenway maintenence brought it down – I doubt the gall was a factor, but I’ve wondered.

Lassiter Mill Shows Crabtree at Strength

 

 The previous post talked about Crabtree Creek’s tendency to flood – last week again brought heavy rains over the Crabtree watershed that brought the creek up to the edge of  its large channels.  This also sends an impressive load of water over Lassiter Mill Dam, as seen above.  I shot a video clip of the rushing water from below the tailrace, as linked below.

video- Lassiter Mill dam at high water

What happens at Lassiter Mill vividily and intensely demonstrates what happens lots of places more gradually – the deposition of new soil by spreading flood waters.  This is an essential part of the natural systems of the Piedmont, and our flood control measures prevent the process from periodically enriching the soil with a layer of mud and silt – though the process continues to work just fine in the “waste” lowlands that remain in Raleigh.  An astounding number of these lowlands have become major thoroughfares – roads built relatively later in Raleigh’s long history, on land left undeveloped due to the floodplain.  The Beltline follows the low contours of Walnut Creek, House Creek, Crabtree Creek, Big Branch, Marsh Creek and then Walnut Creek quite precisely as it curves from Cary’s Buck Jones to Glenwood, over the crest of North Hills, and around southeast to Poole Rd and then Lake Wheeler Road.  The water is piped and rushed away from underneath these elevated roadways, carrying its minerals with it.

The suburbs and businesses near these roads certainly don’t need the sediments!  But the stuff has to go somewhere, and these days there is a lot of stuff.  When streams are buffered by a healthy band of water-loving trees and shrubs, erosion material is reduced greatly. In central Raleigh, Crabtree is clogged with lots of dislodged soil, construction materials and unnaturally exposed red clay.   But the deposition process is a vital one, and it gets exaggerated at Lassiter Mill, where the water brings its load of suspended minerals hurtling over the dam and then slows and spreads its course below.  As it slows, it drops much of its sediment load.  The area below Lassiter Mill changes yearly as the creek alternately erodes and builds up materials.  Check out the new load of sand deposited by the recent high waters.

There are several caveats and complications to consider.  This is a large load of sand!  Eight or nine inches at a dose, and not the silt and mud that the plants would prefer. But nature adapts, and the Lassiter “beach” is fun to browse, with a wide variety of weeds incubated from the loads of  soil and debris.  The silt and sand that currently washes down Crabtree is terribly unhealthy for the filtering mussels and other delicate aquatic life.  The red clay that paints Crabtree brown is such a strong pigment that Crabtree often changes the color of the Neuse where it conjoins.

Crabtree builds itself “shoulders”  as it repeatedly overflows, dropping the heaviest particles first as the water disperse into the floodplain.  This is why Crabtree presents such a tall ditched appearance as above at Hodge Road.  The plants arrange themselves in an orderly sequence beside or on top of these embankments according to their tolerance for flooding.

The next time Crabtree rises over it’s banks, put on your rubber boots and check out the glistening mica-rich silt that covers the greenways before the city sends its scrapers to clear it off to the side, where it enriches the plants as well as any landscaper’s mulch.  You are walking in the stuff that makes our floodplain soils, a rich muck delivered by the yearly floods.

Walnut Creek Wetland Center opening

Walnut Creek Wetland Center_1_1

Numerous city and parks officials joined a large crowd of citizens for the ribbon-cutting ceremony celebrating the opening of  The Walnut Creek Wetland Center.

 Dr. Norman Camp listened to Mayor Charles Meeker, city councilman James West and park officials speak about the new center.  Then the founder of Partners for Environmental Justice , and the man who sheperded this project into being, got up and spoke of the center as a shining new gem in Raleigh’s crown,” as quoted on Raleigh Eco News.

The crowd listened attentively as the benefits for Southeast Raleigh as well as the ecosystem were described and the many supporters and participants were thanked.  Then they were rewarded with a magnificent poem written for the occasion, by Christopher Rowland, a Southeast Raleigh native who wows the crowds at Artspace’s Stammer under the name Langston Fuze.

Musicians entertained on the “longest back porch in the Southeast,” and Erin Sterling, architect of record for the project from Frank Harmon Architecture, explained the details of the green design.  The building is 230 feet long and narrow so that all rooms get light from two sides and often three.  It is sloped up to the north and shelters its southern exposure with the long low porch roof.  Raleigh’s final budget did not allow for the planned rainwater cisterns, but they can come later and the gutters now direct into bioretention areas – long rain gardens that surround the space.  The building is on stilts and allows natural water flow under it – important in this floodplain.  Recycled lumber and building materials were used when possible, and native plantings surround the site.

On the other hand, several of us gazed from the wonderful porch at a huge stand of Microstegia (bamboo or stilt grass) just at the edge of the construction clearing and bemoaned a bit the vast future work entailed in continued future protection of this site and may others in Raleigh.  The educational center will raise awareness of those issues, and provide a much needed amenity and attraction in this part of Raleigh.

Thanks for all your work, Dr. Camp!

I recently had an opportunity to document the Southern Living photo shoot of one of Raleigh’s most interesting residential landscapes.  The Southern Living article about the moss garden at the Urquhart residence on Marlowe Drive will come out in about a year – we’ll return to that incredible piece of landscaping, and promote the article, closer to the publication date.  In the meantime, I wanted to introduce Raleigh Nature readers to David Spain, Richard Urquhart’s son-in-law, who has cared for the property since Urquhart’s passing in 2008.  David follows Raleigh Nature and has been very encouraging of my efforts to portray the Lassiter Mill section of Crabtree Creek, which adjoins the Urquhart property.  This post shares some of his photography and offers a sneak peek at the moss garden, which senior writer Steve Bender at Southern Living describes as the finest he’s ever seen.

The landscape of the Urquhart residence is unique in several respects, and David Spain is keenly aware of the ecological and geological wonders of the place.  The property slopes down steeply to the deep stretch of Crabtree Creek just northwest of the dam.  There is a rich stand of mountain laurel on the slope, and above the moss garden and water park of large pools, waterfalls, and huge rocks.  The rocks were unearthed by creek erosion out of the slope, and the Urquhart family has pried them out, hauled them up the hill, and used them to create a magnificent setting for the plants and water.

David puts into Crabtree in his canoe about as often as I THINK about doing it – which is pretty often- and gets some great pictures, which he has shared and consented to have on the site.  Enjoy some great sights of Raleigh Nature courtesy of David Spain, whose hard work and dedication is maintaining one of the most interesting and valuable residential natural areas in central Raleigh.

What a brave poplar tree!  David can walk the creekside and offer endless lore and history about the area.  His contributions and friendship have been a big reward for my work on Raleigh Nature.  Below is his picture of the Urquhart front yard.  I’ll share my own photography of the site when it’s time to celebrate the Southern Living shoot, which was arranged by local super-gardener Helen Yoest, whose acquaintance I made at the shoot.  Her Metro feature on the Urquhart garden is a great introduction to the site, and it will be fun to see how Southern Living shows off the garden and David’s meticulous work with the moss.

A related fun tidbit:  I received a while back the photo below, which depicts what the senders states are gears from Lassiter Mill.  He asked for advice about who might be interested or what might be done with them.  I thought I would post the picture and give my contacts at the Raleigh History Museum and Yates Mill Park a heads-up.  Any ideas?

News, Notes and Another Promise

The Natural View

The Natural View

Why I have posted just once a month for 3 months:

Best reason – my new column on nature and environment at Raleigh Public Record.

Very good one: I have been documenting The Bain Project, posting like a madman at Raleigh Rambles.  The Bain Water Treatment Plant has plenty of relevance for Raleigh Nature, as it used nature’s own filtering process – gradations of rock and sand – to clean water drawn from Lakes Raleigh, Johnson, Benson, and Wheeler.  It and the more ancient pumping  station which served as the city’s first water facility sit beside Walnut Creek (more about Walnut Creek below).  Just behind the Bain facility is a wonderful greenway deck that traverses wetlands strewn with swamp mallow,  huge white blooms that startle in a sea of southern green.

 Good news: I have more time now, being a teacher, and I also hope to bring Raleigh Nature readers some neat photos from our anniversary weekend in Charleston and our upcoming trip to Bar Harbor and Mount Desert Island.  My promise is at the end of the post.

Walnut Creek greenway at Rose Lane

Walnut Creek greenway at Rose Lane

Lots of happenings around the greenways.  The section that follows Walnut Creek  parallel to Poole Road got flooded Tuesday June 16, along with Rose Lane and other roads near the creek.  The NandO story about the flooding was being followed up the next day by Josh Shaffer, who I met walking Rose Lane when I went to photograph the high water on the greenway. He was hoping to chat with some of the folks who are stranded by high water once every year or so at this dead-end extension of Rose Lane across the creek. I remember quite well my teenage years when Rose Lane dead-ended into a meadow well short of the creek, because we used to drive down there to park in what seemed like deep country in the sixties. Whoever decided to build houses past a perennial wetland with no outlet is the real problem, but the curent residents are facing the consequences.   Josh covers lots of interesting stuff for Nando, from Legos to beloved beer slingers to taking small children to play in cemeteries.  His recent story on kayaking Crabtree Creek   really struck a chord, with its realistic description of the grit, mud and smells encountered on the creek, but I prefer the much quieter section of Crabtree above Lassiter Mill for canoe jaunts.  Getting back to poor Walnut Creek, the heavy rains that caused flooding also sent 15,000 gallons of untreated sewage into the creek upstream in Cary, but the Nando story said no fish kills had been reported.

Newsflash from NandO:  the 4 inches or so of rain also did damage at Yates Mill Pond, pictured above, which has temporarily closed the millsite and trails. Repairs are expected soon.

Lonnie Poole golf course_1_1  The new Lonnie Poole Golf Course around Lake Raleigh is mostly finished and expected to open in July. I posted dismal views and comments about this project in February 08, but when I stopped by recently I felt a little better.  There are lots of wooded buffers, especially next to Walnut Creek, and I must admit the course is looking pretty.

The Fletcher Park water garden is being fine tuned.  Apparently the water level, though quite low down in the retention ponds, was too high for some of the plantings, so a crew came in and extended a kind of penisula of land into the lowest pool, as you can see below.  The crew that explained this to me were taking survey sightings to appraise the work that had been done.  Many of the original plantings had been shifted to higher ground.

The ponds still look pretty muddy to me, but I know time will do wonders. They had an opinion on one item that had been bugging me since the NandO article – springs.  There are no active springs in Fletcher Park, just surface water from the neighborhoods and seep from the ball fields.  Fletcher Park’s lilies are in full bloom!

There!  All the nature news fit to post.  I can’t promise any certain frequency of posts, but I promise to stay totally committed to getting fresh postings up about nature and wildlife inside or near the beltline.  See you on the greenways!

The Walnut Creek Greenway

State Street Greenway Violets

   From the southern edge of the Carnage Middle School campus, or across from the old water station on Wilmington Street you can access a string of highly varied greenway segments that soon will connect Centennial Campus and the Walnut Creek amphitheatre complex.  Due south of downtown, this stretch witnesses the joining of Rocky Branch with Walnut Creek just east of Wilmington, as well as the final taming and flattening of the Walnut Creek watershed as it approaches the Neuse.  Lots of marshy wetlands, including one right behind Womens’ Prison where a greenway viewing deck offers red-shouldered blackbirds, hawks and (after the drought) some unusual wetland plant species.
