Introduction to Habitat Gardening

Introduction to Habitat Gardening
by Glenn Olsen

Gardening for birds and butterflies is growing increasingly popular with urban and sub-urban homeowners, especially during our stay at home period. This style of gardening utilizes plants (especially native plants) that benefit birds and butterflies. Additionally, we want to build structure in our yard, that is, plant in a way to create habitat, places where birds or butterflies feel safe, find food, rest, build a nest or seek shelter. This structure is similar to the way plants grow in nature.

In addition to the beauty and joy of having birds and butterflies in your garden, it can be-come a retreat in which you can relax, enjoy and contemplate in your own nature oasis. Our winter months are a great time to get organized for a spring garden or landscape project. This is the time to plan which plants you want and where you want them in your yard. Also, if any flower bed preparation or pathways need to be created, winter is a good time to get that done.

The Upper Texas Coast is part of the migration route that many of our songbirds use as they migrate to and from Mexico, Central and South America each spring and late sum-mer. We can attract many of these weary migrants to our gardens by adding plants that provide food and shelter and create stopover habitat during their travels. Some of the beautiful birds that you may attract during spring migration are Summer Tanagers, Rose-breasted Grosbeaks, Ruby-throated Hummingbirds, and Warblers, the jewels of our birds.

Here are a few of the more commonly available native plants that provide food and shel-ter for many of the birds that migrate through or spend the winter on the Upper Texas Coast. Each of those listed grows well in our area. Additionally many of them are valu-able and important to our native, beneficial pollinators and butterflies. This is only touch-ing on the plants available, there are many others. Be sure to purchase the plants based on the botanical (scientific name) because there are similar non-native plants that grow much larger and/or do not provide the food like the native plant.


Yaupon holly (Ilex vomitoria) and Possum-haw or Deciduous holly (Ilex decidua)
Two medium sized shrubs that grow well and are attractive in a landscape that produce bright orange to red berries that many birds feed on. In the spring they have many small white flowers that attract numerous beneficial insects.


American Holly or Christmas Holly (Ilex opaca var. opaca)
 
This classic American evergreen tree is under utilized in the landscape. The attractive red berries are produced on the female plant, so make sure yours has the berries when you buy it. The berries are important food for many species of birds during the winter and it also provides important shelter from the cold. American Holly is a very stately and attractive tree that would add character and beauty to any landscape.


Rusty Blackhaw Viburnum (Viburnum rufidulum)
This attractive plant with its shiny, dark green leaves is usually an under story shrub of up to 12 feet but if planted in full sun may grow to about 30 feet. In the spring it produces large clusters of small beau-tiful white flowers. In the fall, the bluish black fruit is consumed by many species of birds. Another good shrub that provides shelter for birds in inclement weather. This plant will add year round color to you landscape.


Arrowwood Viburnum or Arrowwood (Viburnum dentatum)
This is an excellent under story shrub that grows 4 to 10 feet tall. It has a nice open and airy appearance, which provides an attractive visual aspect. The bluish-black fruit ripens from August to November and provides much need food for fall and winter migrants


Turk’s Cap (Malvaviscus arboreous var. drummondii)
 
This beautiful shrub grows in the eastern half of Texas as well as in other states along the gulf and south into Mexico. This hardy shrub grows in all light conditions from heavy shade to full sun. However, shade to filtered sun are the preferred light conditions. It grows in many soil conditions from the salty sand along the coast, the heavy gumbo of Houston, and the dry, rocky soils of central Texas. It is drought tolerant too! In heavy shade this plant grows low to the ground and in sun grows up to four feet tall but needs more water. However, the height it is easily managed by trimming back during the winter. Turk’s cap is at the height of its bloom period during the fall migration of the Ruby-throated hummingbird. The bright red flower resembles a rose bud (or turk’s cap). But like other members of the hibiscus family, the stigma extends above the flower petals. Make sure you purchase the native (Malvaviscus arboreous var. drummondii) and not any other. The other species will grow to ten feet tall and is reportedly less frequented by the Ruby-throated Hummingbird.


Blue Mist Flower (Conoclinium colesetinum)
The gorgeous pale blue flowers of this medium sized leafy perennial is a magical nectar source for many species of butterflies. The ageratum like blossoms grow at the tips of the stems and are so abundant they cover the entire top of the plant. Hummingbirds and pol-linators also make good use of these flowers. Easily grown in light shade to full sun in various soil conditions. Growing from about 16 inches to 26 inches tall ( but can grow taller) these hearty misflowers are an attractive addition to any landscape.

The plants mentioned are only a few that contribute to a colorful, attractive garden or landscape and help create habitat for birds and butterflies whose presence softens the urban environment and creates a more enjoyable and interesting yard.

Creating a Pocket Prairie in an Urban Backyard

In September of 2017, my girlfriend Amanda and I, along with our dog Scout, moved out of our apartment and into a house in Houston’s Sunset Heights. One of the selling points of this house was that it had a small backyard the three of us could enjoy together. It was a simple space comprised of zoysia grass, Japanese yew, and bamboo. In June of 2018, Scout was sniffing around our backyard and decided to eat a couple of Japanese yew berries that had fallen on the ground. This led to her getting sick and spending the next two nights recovering at a veterinary clinic. This is the event that made me start to question everything growing in our backyard. Why did we have grass, shrubs, and bamboo from Asia? Why had we never seen a butterfly in our yard? We decided we needed to make some changes. To begin my research, I read The Houston Atlas of Biodiversity by Houston Wilderness, Bringing Nature Home by Douglas W. Tallamy, and Native Texas Plants by Sally Wasowski and Andy Wasowsk

Critical habitat is closer than you think - Rice University students create a Habitat Conservation Plan to support wildlife in our city

Across the world, species are rapidly disappearing before our eyes. This is a biodiversity crisis. Urbanization has caused habitat degradation, loss, and fragmentation, which contribute to the decrease in global biodiversity. At Rice University, fifteen students signed up for Dr. Cassidy Johnson’s Conservation Biology Lab in hopes of making changes on their campus and in their city to protect and enhance the local biodiversity. These students are creating and communicating their desires to implement a Habitat Conservation Plan at Rice University in order to contribute to urban conservation efforts right here in Houston. Their project tackles specific biodiversity concerns including critical habitat, bird conservation, pollinator gardens, medicinal gardens, carbon sequestration, and wetland restoration. The following piece is written by students in the Conservation Biology Lab who are taking part in developing that plan. This is the first post in a series. ----- When people walk

Houston, we have an announcement. We’re now a Bird City!

We know that Houston is a vital city for birds, but now it’s official . Houston Audubon’s Conservation Team worked tirelessly in partnership with Houston Parks and Recreation Department (HPARD) Natural Resources Program to submit the application, and it paid off. Houston was honored as one of the first four cities to receive the Bird City Texas certification – an inaugural program by Audubon Texas and Texas Parks and Wildlife Department (TPWD). So, what exactly does being a Bird City mean? The big picture is that we have demonstrated that our community cares about birds, habitat, and conservation. The growing popularity of planting native plants, restoring prairies, bird-friendly education programs, and the Houston Lights Out for Birds program to reduce collisions for migrating birds were among the many efforts and programs that got us this designation. ( Go Houstonians! ) I personally witnessed the large amount of work that went into this application and was curious about
