Natural Resources

The Houston Parks and Recreation Department is committed to preserving and protecting the natural resources of the City of Houston’s park system for present and future generations. To this end they have tasked the Greenspace Management Division with the creation of the Natural Resources Program (NRMP) to manage the oversite of the department’s natural areas within parks.

The Natural Resources Management Program (NRMP) works to preserve the biodiversity and natural heritage of Houston and surrounding areas by supporting green space preservation, protecting and restoring natural communities, and cultivating a sense of environmental awareness through research, education, and stewardship. Within Houston’s urban environment, there are significant green spaces and natural resource areas. HPARD owns and manages an extensive network of parks and green spaces including 381 parks encompassing over 25,000 acres in and around Houston. Of those 381 parks, 80 have been identified as having natural areas, which total over 16,000 acres.

Resilient Houston focuses on the pressing challenges and opportunities that will shape Houstonians’ lives today and for future generations. Their are18 Targets outlined in the strategy that will be used to measure the impact of Resilient Houston.

One of the targets that is currently being implemented is the planting of 4.6 million new native trees by 2030.

To track progress on the 4.6 Million tree planting goal, the Houston Parks and Recreation Department is hosting the Resilient Houston Tree Planting Portal to collect data on all tree plantings within the City of Houston.

To register your tree planting on Resilient Houston Tree Planting Portal please fill out the form at https://forms.office.com/g/C5FvvMSsWb.


The Natural Area Ordinance was created under Chapter 32-10 of the City of Houston Code of Ordinances to address natural area creation on private land. This allows for citizens to create and maintain natural habitats, including native plantings in their yards. There is no requirement that a Natural Area Permit be obtained prior to the creation and maintenance of a Natural Area. However, the existence of a Natural Area Permit can be a defense to a complaint or prosecution for violation of City ordinance. If you would like to create wildlife friendly habitat in your yard, please see the links below:


The NRMP is currently working to create a Nature Preserve designation for parks with significant natural resources. This initiative was announced in Resilient Houston as a way to support the region’s land conservation goals. Our Nature Preserves will be protected from development to ensure that their ecological and recreational value remain intact. Twenty-six parks and over 7,500 acres are currently targeted to receive this designation. See below for a list of the proposed nature preserves and check back soon for links to park maps!

Blackhawk Park Brock Park Cambridge Village Park
Clinton Park Cullinan (J.S. & L.H.) Park East Tidwell Park
Farnsworth Park FM Law Park Freed Art & Nature Park
Herman Brown Park Hobart Taylor Park Keith-Wiess Park
Lake Houston Wilderness Park Maxey Park Robert C Stuart Park
Sylvan Rodriguez Park Taylor (E.R. And Ann) Park Tidwell Park
Lorraine Cherry Nature Preserve West Mount Houston Park White Oak Parkway
Woodland Park Furman Street Greenspace South Main Estates Park
Sheldon Park Eisenhower Park  

Historically, Houston’s bayou systems were outlined with strips of forested habitat, and the trees along the waterway would stabilize the banks of the bayou, improve the water quality, and provide wildlife habitat. Through the Riparian Restoration Initiative, the NRMP will install new riparian forests or will improve the quality of existing riparian forests across the city, reaching over 70 parks and 1,000 acres of park land. This initiative was announced by the Mayor in February 2020 and was included in the Houston Climate Action Plan.

Prior to the settlement of Houston, the dominant habitat of our area was Coastal Prairie, an ecosystem characterized by large bunch grasses and colorful wildflowers. Prairies depend on herbivores, like the American Bison, and frequent wildfires in order to thrive. Without these forces, prairies can easily turn into forests dominated by invasive species. Coastal Prairie habitat has declined due to development and human intervention and is now one of the rarest habitats in North America. The NRMP is actively restoring prairie habitat in five city parks! Click the links below to learn about our prairie restoration projects:
  • Sylvan Rodriguez Park
  • Robert C. Stuart Park
  • Clinton Park
  • Hobart Taylor Park
  • Blackhawk Park

The Houston Parks and Recreation Department recently created the Tree Protection Committee, a collaborative group of parks staff from both Urban Forestry and Natural Resources. The Tree Protection Committee began a review of the Street Tree and Park Tree ordinances and has created a new species list for tree plantings. The new tree list will ensure that only native tree species are installed in our parks and streets. Native species are well adapted to our climate and therefore will require less water, provide habitat for wildlife, and will survive in the harsh urban environment. Check back soon for the new tree lists!

In 2016, Mayor Turner signed the National Wildlife Federation’s Mayor’s Monarch Pledge! The City of Houston has committed to take action to help save the monarch butterfly, whose population has steeply declined over the last two decades. The Natural Resources Management Program is working on meeting the action items identified in the pledge. The action items involve community engagement, demonstration gardens, habitat creation, and systems change.

The City of Houston is currently meeting the following action items:
  • Yearly participation in a native plant sale along with the Houston Arboretum & Nature Center and Houston Audubon
  • Milkweed seed collection and propagation.
  • Native garden planted at the City Hall Annex with milkweeds and other native plants.
  • Completed the NWF Community Wildlife Habitat Certification.
  • Pollinator plants and milkweeds included in several HPARD Community Gardens.
  • Active invasive species management in HPARD’s prairie restoration sites.
  • The Natural Area Ordinance (Ch.32-10) allows for citizens to create a more pollinator friendly habitat in their yard, by reducing the restrictions on mow height.
  • Park policy amended to only allow for native tree species in city parks and streets.

View all Action Item descriptions here.


The NRMP is currently working to map out all of the nature trails in our parks. Please see the links below for the maps that have been completed so far, and make sure to check back as we add more! We hope you can use these maps as inspiration to check out new parks and experience nature.


In 2020, the City of Houston was officially certified as a Bird City Texas Community by the Texas Parks and Wildlife Department and Audubon Texas. Bird City Texas is a new certification program that recognizes leadership in bird conservation and community engagement.

The City of Houston, led by the Natural Resources Management program and in partnership with Houston Audubon, applied for the certification by compiling various bird conservation and education efforts throughout the city. Moving forward, the Natural Resources Management Program will continue to work on meeting the objectives involved in our certification. Learn more about Bird City and other bird-related topics below.
