Brenda Pennington and Thomas Collins of Urban Gardeners are the brains and brawn behind this wildlife habitat tucked into the middle of River Oaks. This property was an empty lot until 2001. The owners wanted to keep much of the exiting vegetation and create a wildlife sanctuary.Wildlife Sanctuary in River OaksMay 9th the Height Garden club did their monthly tour and Brenda was our guide and Thomas was keeping us together and if you held back you could ask him questions too.Wildlife Sanctuary in River OaksThe 2 acre property is a wealth of native plants. The process to create it was part editing, thinning and clearing, especially of invasive plant species. Thomas and Brenda each have their own specialty in their business partnership. Thomas does the lay out, the path, pond, fences and other hardscaping. Brenda knows the plants.Wildlife Sanctuary in River OaksThe have been working on this garden since the beginning. The back of the property is still much as they found it. The architects were responsible for the stone house and driveway and the gardeners did the rest. The front face on Inwood Drive is 350 feet. IMG_8761Wildlife Sanctuary in River OaksBrenda is not fond of crape myrtles, azalea and ligustrum which are the backbone of many gardens in River Oaks. She did say this is a very high maintenance garden and it takes 3 people to keep up with it.IMG_8770Wildlife Sanctuary in River OaksShe collected a high number of these plants. It has been a trial and error evolution. Brenda found that not all the native plant worked in this space. She used resources like the Native Plant Society of Texas NPSOT and prairie rescue groups, like the Native Prairies Association of Texas, in the process of creating the different areas like the prairie meadow and the banks of the pond and stream bed.IMG_8812http://npsot.org/wp/houston/Identifying the right mix of plants to create these little ecosystem has been a learning experience. Finding out along the way that just as Texas is a big state ‘Texas natives’ is a big group but many only grow in little micro climate areas in our big state. Native plants can also be thugs built to propagate. Initially they went to places like the valley down by the border but they found that many of these plants could not adapt to our rainfall which is about 22 inches more than Brownsville. You catch just a glimpse of the front wall of the house in this photo.

Houston is part of the Tall Grass prairie. We saw Indian grass, little Bluestem mixed in with Ground Mimosa, Winecups, Prairie verbena, Cherokee sedge just to name a few. The metal is a fine complement to the wildflowers. IMG_8792Wildlife Sanctuary in River Oaks We came across wonderful art details reminding us we are really in someone’s garden.IMG_8790Wildlife Sanctuary in River Oaks You will find only one open grass area and there they used Buffalo grass. The entire right of way is also planted in Buffalo grass mixed with other little creeping plants. Brenda pointed out that in nature grass doesn’t grow as a mono culture.IMG_8782Wildlife Sanctuary in River Oaks Up close of the grass in the right of way.IMG_8910Wildlife Sanctuary in River Oaks The only thing between the property and Buffalo bayou is the country club. Unfortunately a few years ago they located a 3 story parking structure right behind the property cutting off access for wildlife to and from the bayou. They estimate this cut their wildlife count by 50%. IMG_9072 Wildlife Sanctuary in River Oaks They still have plenty of lizards, Red ear slider turtles, Leopard frogs, green tree frogs and some Eastern Narrow Mouth toads. They get possums, armadillos and that morning someone saw a Ribbon snake near the stream.  They did a great job of making this look like a real stream. IMG_8825Wildlife Sanctuary in River Oaks There are other water sources for wildlife through out the property like this orange dish positioned under a dripping hose. IMG_8827Wildlife Sanctuary in River Oaks The tall canopy of trees support large birds like hawks and owls. Over 70 species of birds have been spotted here. There is a honey bee hive in an old tree and they have observed many native bees especially in the prairie area and around the pond.IMG_8808Wildlife Sanctuary in River Oaks As we walk beside the stream we head down a path made with pine needles. It leads to the less managed part of the garden. IMG_8836Wildlife Sanctuary in River Oaks We were asked not to photograph the house but I wanted to show part of the pool so you can see that the home is entirely surrounded by nature.IMG_8835Wildlife Sanctuary in River Oaks Another thing they battle is the effects of nearby “mosquito misting systems” that harm pollinators along with the mosquitoes. I wish I could have done a video of Brenda acting out a convulsion butterfly dying from the effects of chemicals. There is always natural death in a ecosystem like this hawk strike. A reminder that sacrifices are made to continue the cycle of life. IMG_8843Wildlife Sanctuary in River Oaks This lead into a conversation about things like people dumping their exotic Asian Carp in the bayou when they decided they are done having a pond. And how invasive plants get introduced. It can disrupt an ecosystem whether it is a disease, plant or animal. “But it’s so pretty!” are her 4 least favorite words. Natural beauty is at work here and it was an amazingly tranquil place. It was hard to remember we were surrounded by big mansions.IMG_8786Wildlife Sanctuary in River Oaks These days they find they are planting less and have become editors keeping a level of order. And she reminded us “Critters don’t care if it is neat and clean.” They do battle things like cedar hawthorn rust. They have been using a soybean oil and sulfur spray on leaf outbreak occurs. “Everything you do has unintended consequences” say Brenda. For instance aphids which they sometimes control with a hard spray of water from the hose. But they don’t want to spray where they can’t see what damage they may be doing to other beneficial insects. Other times they let the chain of life do its thing.IMG_8847Wildlife Sanctuary in River Oaks As we head into the wooded area with some oaks and pines we have to stay on the path because there is an undergrowth of Cherry laurels and other undergrowth. Cherry Laurels came in the sunny spots left when the property lost 27 trees including all the oldest “Granddaddy trees” as Brenda referred to them. She said you could see the swath of damage across the property with everything topped if not downed. They left the down trees to become nurse logs for seedling tree and homes for insects and other wildlife. They keep the Cherry Laurels in check because they choke out the light for other tree seedlings. They also leave piles of brush for birds to hide in.IMG_8844Wildlife Sanctuary in River Oaks There is a simple irrigation system that uses water from a 350 foot deep well. In the worst of the drought they did use supplemental water more regularly than they would have preferred. Not wanting to disturb tree roots not all the property is irrigated and the back is waters with rotors. They would do periodic deep watering for 4 or 5 hours.IMG_8876Coming back out to the small pocket prairie we stopped to identify more of the plants. Here is an interesting article about the pocket prairie movement in Houston. Here are just a few that I got pictures of. Erigeron annuus (L.) Pers.

This was an amazing tour and I wish I could do a one on one with Brenda; I had so many more questions. It was wonderful to have so many people join us and the growing interested in urban wildlife habitats. The one thing I was not as familiar with was the important of the prairie in Houston.
TOP 10 FACTS ABOUT…THE PRAIRIE SYSTEMS from http://houstonwilderness.org/
1) The Texas coast once held 6.5 million acres of prairies, thick with chest-high grass that supported enormous numbers of prairie chickens. Less than 1 percent of these acres remain.
2) Of all of the ecosystems in the Houston Wilderness, prairies are the most endangered. They have been overgrazed, plowed and otherwise developed nearly out of existence.
3) Although from a distance they may look monotonous, up close prairies are a shining example of biodiversity with an intricate chain of relationships that naturalists are still working to understand.
4) Plant life, like goldenrod, asters, dewberry vines and native grasses, and feet-thick clay soil help the prairies function as a retention pond – preventing flooding in the surrounding areas by helping water percolate down into the water table instead of running off.
5) Prairie grasses can be difficult to identify, even by grassland experts, because of their diversity: there can be 25 different kinds of the same grasses, differentiated only by the seeds of the flowers it produces.
6) The grasses aren’t the only species in the prairies, rare and beautiful birds all thrive in this habitat. The ground-dwelling Henslow’s sparrow and the secretive sedge wren can both be found in local prairie systems.
7) The Katy Prairie stretches from the Houston city limits west to Brookshire, northwest to Hempstead and southwest to the Brazos River. It encompasses over a thousand square miles.
8) Many animals call the coastal prairies home, including the burrowing owl, raccoon and seasonal residents, snow geese.
9) In the spring, prairies are known for their lively, shimmering fields where tiny flowers dot the landscape.
10) The Prairie Chicken, once abundant, is now perilously close to extinction – most birds are raised in captivity. The Attwater Prairie Chicken National Wildlife Refuge exists to help restore the breeding population of these native birds.

I hope you enjoyed the tour! I leave you with one last photo of a precious little fuzzy flower whose name I did not get. IMG_8850Happy Gardening…there is always room for natives!
