I have a small plot of D. Brevifolia on my property located half way between Houston and San Antonio, Texas on an eroded and depleted plot of less than 100 sq ft in a cattle pasture. I have not found any citations of other population in my area or basically anywhere in Texas other than in the eastern wet areas near the Louisiana border. I have searched my land and the land around mine and found no other specimens.
I have no idea how these plants are surviving the hot, dry summers and have come through some severe droughts that have killed many of my mature oaks. I noticed them when I purchased the land 10 years earlier and have observed their absence in the summers and entirely during drought years only to have them re-emerge on wet years like this year. Other than the depleted soil, I see no beneficial attributes to the Drosera in this area or how they established a population let allone survived the harsh conditions (climatic, human and cattle including fertilizers and herbicides).
Does anyone else have knowledge of native populations of drosera brevifolia in central Texas or under similar conditions?
Just an update. Found a second larger patch in February 2016 thriving a few hundred yards away. It has been a very mild winter, but my original pack is dormant and the new one is not. Same general environment; highly eroded sandy spot in a cattle pasture where almost nothing else can grow.
Last spring I tried to transplant some to a grow box I use for my other carnivorous plants. The lived for a few months, but never grew and eventually died. I'm going to try again this spring.

I know that they live in and around Houston TX. Do you live in the Brenham TX area? I am Originally from Austin TX but have seen Brevifolia east of the Capital. That is very cool information kkaase! Keep them growing evidence suggests they will survive?

D. brevifolia is known to be able to die back to the roots and survive harsh conditions that way, usually deep freezes in places like Tennessee or further north. Could be this is how they're surviving your conditions.

It is so Hot in Texas all over the state. I have no idea how any animals or plants survive. All the droughts we have had. Snakes come up to water spikits to survive. That is why on the outskirts of Houston people have been getting bitten by copper heads. The deer and wild hogs eat acorns because they have no other food source and the meat tastes bad because of that. From Austin to Houston a few years back trees would get so hot and dry they would combust into flames and start fires. So how any Carnivorous plants survive is a miracle? It has to be that the dews can die back hcarlton. I here florida is having the same things. Loosing populations of CPs becuase of heat and drought.

Couple of incorrect things there: one, there is no way it gets hot enough anywhere on the planet for things to spontaneously combust, so the only way those plants are igniting is if something sets the fire. And two, people get bit by snakes because they are not alert enough to watch where they're going and miss the animals or are trying to handle the animals, not just because they happen to be in the same area. This is beyond the fact that it's just about impossible to die from a copperhead bite, the venom is too weak.
But, that's beyond the main point of this thread. If there are multiple years of full drought then the plants would die even from the roots, but from even personal experience it takes a long time to sprout >D brevifolia seeds, so they likely persist via a dormant seedbank until conditions.

First and foremost smarty pants hcarlton trees do combust under heat look it up on wilkapedia or any others source on combustion. They combust under built up bacteria inside the tree that gets hot from the sun then burst into flames Have you ever heard of composting that explodes probably not. Same thing as the trees.. Also you are not from Texas you don't know evidently what goes on there?? You probably need to do some research before you call someone out. One more thing I was into herpatology and went to Texas A&M for my studies. Snakes do and have attacked people depending on the specific species of snake. For instance king cobras and many types of cobras have delebratly come from no where and bitten people. Other snakes that can be dangerous and attack you are cotton mouths black mambas evan non venomous rock pythons. You are very disrespectful to people who have been bitten by these snakes by saying it is always there fault. Also where did you come up with me saying peoole died from copper heads? You are not very observant. Your comments just showed that you do not have knowledge of reptiles especially snakes or trees for that matter. You evidently have never seen an aggressive snake before. Think before you speak hcarlton you don't sound intelligent when you do!! You must be bored making up facts. Keep reading facts on the world or go outside sometime and see it for yourself. Good luck to you.

Education on the facts before you speak is a good idea!!:thumbdown: |

Been educating myself on facts of nature for a decade and a half now, with specialization in snakes and carnivorous plants, as well as various odd facts (dry paper ignites at 451 F, plants would take an even higher temp unless highly oily species, for example). What I said stands.

Organic decay can produce phosphene, diphosphene and methane gases. Mixtures of phosphene and diposphene ignite in contact with oxygen which in turn could ignite the methane. High temperatures would increase the rate of decay and also dry out dead vegetable matter increasing the chance of combustion.
