Houston conservationist is helping to find new ways to protect local species and ecosystems

The Houston toad is a species that was discovered in Harris County in the 1950s. It has a very distinct, loud call that reverberates at quite a high pitch. But the Houston toad's call hasn't been heard in the city of Houston for almost 50 years. The species is locally extinct and critically endangered elsewhere. In fact, it's the most endangered amphibian in North America, says Cassidy Brown Johnson, a Rice University lecturer and president of the Coastal Prairie Partnership.

"When we think about extinction, we think of the dodo bird or the woolly mammoth," Johnson says. "But extinction is happening right underneath our noses."

The Houston Zoo has a breeding facility for Houston toad, but other than that, it's extremely unlikely that the Houston toad will ever reside naturally in its namesake city.

"We have modified the environment so heavily, that it'd be a bit of a dicey thing to do [to reintroduce the species] because there are so few of them, it's better to focus on an environment where it's still OK for them," Johnson says. The largest population of the Houston toad is actually in Bastrop, however due to the Bastrop fires in 2011, the species is only just recently back to a good place even there.

Johnson is giving a free lecture in April at Rice regarding extinction, where she'll bring her Astros-named Houston toads, Springer and Julia Morales, as her teacher aids.

Changing tides in conservation
As cities like Houston continue to be developed, scientists and researchers are challenged with finding new ways to effect conservation. Johnson says within the industry, there's been a shift in thinking when it comes to preserving nature.

"There's a new burgeoning movement in conservation called urban conservation," she says. "For a long time, if you talked to the traditional conservationists, the idea of conservation is to protect big spaces — the national and state park systems are the perfect example."

But large parks are expensive and a huge undertaking. It's still the strongest form of conservation, but introducing conservation efforts in a city — perhaps in some of Houston's parks, like Memorial Park or Hermann Park — helps not only the species of animals involved, but also educates the local population and forms a connection with residents.

"That has a twofold kind of benefit," Johnson says. "It protects the greenspace so species to live with us, and then also it makes the connection to this place we try to protect."

Of course, this type of effort is new, and there's not a lot of data to show how this would affect the ecosystem and its species, from the migratory and genetic diversity standpoints. Despite the lack of data, Johnson says this type of effort needs to happen.

"We're going to continue to manipulate the world, and maybe if we started thinking about this now, that we can get to a point were we understand enough were we can make these some sort of functioning ecosystem," she says.

Part of the shift in thinking about these ecosystems has to do with new ways of tracking species and understanding their environments.

"Technology is helping us ask a lot of these questions," Johnson says. "Ecology is surprisingly complicated. There's so many variables. ... I think technology and our advance with computing is definitely going to help us understand it."

Using preservation to solve flooding
The educational component is also very important to conservation, and Johnson is making strides on campus with her class. Last year, her department and her class introduced a pocket prairie right on the Rice campus.

Before it was the fourth largest city in America, Houston was a prairie. That type of ecosystem — thick with prairie grass — is very absorbing when it comes to rain water.

"It's really surprising to people that the trees and all this lushness is actually all artificial," Johnson says. "We know that this ecosystem evolved with the cyclical flooding events that happened here."

This movement to bring back Houston's ancient ecosystem is a new focus on a few prairie conservationist groups — and even the Harris County Flood Control. This has been going on for a while, but recent flooding events have opened the eyes of people now looking for reliable solutions to flooding problems.

"After Hurricane Harvey, people started realizing that this might be one of the solutions we could actually investigate and see if it can help us," Johnson says. "A green space is going to absorb way more water than a parking lot."

Of course, there are other flood solutions being discussed — some even incorporating tech or even a tube system underground.

"Historically, there has been some budding of heads between the environment and technology, but I really think moving forward, those two fields have to work together. We need to use technology to save the environment," Johnson says. "I think Houston is one of the places where that conversation is starting to happen."

Building Houston

Houston Exponential has hit launch on the HTX TechList, and now startups, investors, entrepreneurial hubs, and corporations can officially opt into the data-focused and networking-enabled platform.

The HTX TechList went live yesterday, August 13, at a virtual event hosted by HX. (Note: InnovationMap was the media partner for the event.) The platform acts as a one-stop shop for Houston's innovation ecosystem. Mayor Sylvester Turner joined the stream to explain the role the platform will play in connecting the various players within the industry.

"The HTX TechList is our city's leading resource for in-depth information about Houston startups, investors, hubs, and corporations," Mayor Turner said at the event. "Within the Houston region, the HTX TechList will build the connections and density that were never before possible in such a huge spread-out city."

Another benefit to the new platform, as HX Chief of Staff Serafina Lalany says, is the data it is going to be able to provide about the ecosystem.

"We needed a centralized datasource classifying startups, investors, startup development organizations, and corporate innovators," she says on the Houston Innovators Podcast. "There was not any good resource on the internet that was verified, centralized, and adhered to a data standard."

The platform, which has derived from an initiative from Startup Nation Central in Israel, has already proven its usefulness abroad and has over 70,000 monthly users. In a panel at the event, Eran Levy of Enel Innovation Hub Israel described how the tool has benefitted him and his work in scouting startups.

"The ability to have a tool to map, in our case, 8,000 startups, when we look for specific categories or a specific tech area, it helps us a lot," he says. "It saves a lot of time and effort, and, more importantly, it makes it much more effective because I reach out to the right startups."

On the panel, Barbara Burger, president of Chevron Technology Ventures and chair of Houston Exponential, echoed the opportunity for connectivity the platform will enable — but in a specific way for her organization as an investor.

"I view the TechList as the tool that's going to enable a couple of things. One is the scouts to access even more opportunities, but I think the other piece is also for co-investors in startups to be able to find us," she says, adding that while CTV has been around for a couple decades, visibility is always something they'd like to improve on.

Now that the platform is launched, anyone can join to make a profile on the site. Startups, investors, hubs, and corporations can also launch profiles that will be vetted by HX's data team.
