Texas Rolling Plains Bioblitz: 3 Rivers Ranch (May 29-31)

Observations made

Identification portal

Horned lizards are obscured, so here are our horned lizard observations.


If you're reading this, you're invited!

Formerly, this post was for Lake Palo Duro, but due to extreme dought conditions there we've relocated the event for this weekend to 3 Rivers Ranch.

👉 3 Rivers Ranch website

👉 iNaturalist Project

👉 Property boundary map (green polygon is "public area", but we have access to areas outside this--I've indicated some areas of interest outside the public area with yellow pins. These are walk-in only. If parking along paved road, park well off pavement to avoid semi-truck traffic.)
Green pins indicate mothing locations Friday and Saturday nights.

👉 Facilities map (higher resolution version of facilities map)

A variety of overnight lodging is available. Car/tent camping and a coed bunkhouse is no cost. Other housing options are available, but you'll need to cover the cost of those. See their website for more information about those options.

Covered pavilions are available along with an air-conditioned classroom/kitchen facility.

Lynn (@rlseman) is Master Naturalist with the Rolling Plains Chapter and will be our "guide" (point of contact for information) as she knows the property well. Cady the property manager will be on site until 4 pm Friday. There will be a single liability waiver that everyone needs to sign (I assume it will be kept in the classroom/dining hall).

🐍 Rattlesnakes and 🐗hogs are abundant, so take great precaution everywhere you go.

Let's try to keep arrival/departure times between noonish Friday and 1 pm Sunday.

👉👉👉 Please sign up here:

I'd like to do mothing Friday near the cabins and Saturday at the far-south pavilion area (we can drive down there). I've placed green pins at those locations on the property boundary map (above).

Leave a comment and sign up (link above) if you're interested in attending, and tag folks in the comments that you'd like to invite.

North Texas Bioblitz: Birdwell and Clark Ranch near Henrietta (May 8-10)

UPDATE
Here's the link to observations made during the event:
https://www.inaturalist.org/observations?d1=2026-05-08&d2=2026-05-10&project_id=birdwell-clark-ranch&verifiable=any

And here's a link to the identification modal (showing only those that are not Research Grade, which can be changed in the filters):
https://www.inaturalist.org/observations/identify?d1=2026-05-08&d2=2026-05-10&project_id=birdwell-clark-ranch&verifiable=any

I'll give folks a couple of weeks to get observations uploaded, and a couple of more weeks to get identifications. Then I'll write up a report for the property owners.


Dedicated iNaturalist observers eager to document as many species as you can are welcome to join us at the Birdwell and Clark Ranch, a 14,200-acre property of tall grass prairie, river bottoms and brushy draws located in north central Texas in Clay County on the Little Wichita River east of Henrietta (video here). The ranch is a conservation easement with the Texas Agricultural Land Trust. TALT promotes the conservation of open space, native wildlife habitats, and natural resources of Texas’ private working lands.

UPDATE: we'll have an empty house available for us to gather--this will be our headquarters. It has a restroom, three bedrooms, kitchen, porch, etc. It's centrally located and indicated with a blue pin on the property map.

Tent and car-camping, but there is a house with bedrooms if needed (i.e. poor weather).

Ranch road conditions. The main ranch road is gravel, but washed in places. It's not muddy, but it's bumpy. For secondary (non-gravel) roads, please avoid using them unless they are obviously well-used. Don't take the path less taken.

Sign-up sheet:

Tag folks that you'd like to invite.

Find your observations that you probably misidentified

Here's the scenario: you posted an observation, identified it, and then someone comes along and gives a disagreeing ID. There's a good chance your original ID was incorrect. But possible that the disagreeing ID was incorrect. Those observations slip under the radar easily, and it's been difficult to find and revisit them. Until now!

You can now filter observations with a disagreeing ID.
https://www.inaturalist.org/blog/112991

Here's a link with all the options you need to show these observations--just change the user ID at the end of the URL:

Identification resources and iNat tips/tricks

ID guides and curation resources

Insects

Plants

Mammals

Misc.

  • ID modal for things identified only as Arachnids (can edit filter to display observations identified to a different range of taxonomic ranks--first rank box is the highest rank, second rank box is lowest rank). I have it sorted to show oldest posts first.
  • And, of course, one can change the focal taxa and location (e.g. things only identified as beetles in TX). I have it sorted to show oldest posts first.

My projects and stuff

Really interesting things

Timberlake bioblitz events

ID guides created by other folks

iNat Tips & Tricks

It's recommended not to agree to an ID just because someone else gave that ID--only ID things based on your OWN knowledge and research. Let two knowledgeable folks take it to research grade.

iNaturalist Explorer

  • A website to perform search queries that aren’t available in the current iNaturalist Explore and Identify pages
  • See forum post here where it was introduced.

Browser extensions

View specific life stages of a taxon or observations with sounds

Adding annotations

  • Filter observations (in the Identify modal) which don't have annotations (change taxa and place as desired). Click the Annotations tab and use drop downs or keyboard shortcuts (keyboard icon in lower left) for adding annotations .
  • For flowers, chose "no evidence of flowering" if not flowering in order to remove it from future filtering as an observation needing annotation.

Misc.

It's Penstemon season!

There is a region of Texas where Penstemon identification is difficult (west-central TX). Observations in this area of critical features will be important to help clarify the morphological variation within and between species. An undescribed species is possible, or hybrids. We just don't know yet.

Here's a previous journal post focusing on two species and a link to photos/descriptions of key details that need to be documented (along with a map):
https://www.inaturalist.org/journal/pfau_tarleton/77925-penstemon-guadalupensis-and-p-albidus

Please share and tag if you know of folks in or traveling to west-central TX.

October 17-20, 2025: Bioblitz at Independence Creek and Diamond Y (Nature Conservancy properties)

Independence Creek observations are here:

Some notable observations:

Diamond Y observations are here:
https://www.inaturalist.org/observations?d1=2025-10-17&d2=2025-10-20&lat=31.004670947231546&lng=-102.92165899305644&radius=1.0192765721862747


Map showing locations of these two properties here

🚫 Aquatic sampling not permitted.

All roads shown on the map are driveable currently, though the minor roads may require high clearance.



Notes from the Nature Conservancy property manager

The Bunkhouse at Independence Creek has 5 bedrooms, 2 full baths, and a full kitchen. There are 16 beds in all the rooms. Some are bunk beds and there is 1 queen and 1 full. The living room has a large couch and futon where some folks could sleep. One bedroom is empty and some folks could throw air mattresses down if they wanted. The smaller bathroom has a shower, sink, and toilet as well as a washer and dryer. The larger bathroom has a shower/bathtub, two sinks, and a toilet. The kitchen is fully functional with all necessary cooking utensils.

There is also ample room outside if someone wanted to pitch a tent.

In terms of rules, there can be no collecting or sampling of any natural or cultural resources without a scientific research permit from TNC. If y’all are just doing photo vouchers for iNat, then no permit is required.



What to look for
  • Undescribed species of bug: There's a potentially undescribed species of bug that I encourage folks to look for and collect (I'll provide containers). Sam found this one beneath a rock, so let's look under rocks (I have a permit for collecting these).
  • Dark spiders like this one.

Where are the Anemones?

For the 2025 season, February 6th was when the first person documented on iNat Anemone berlandier in bloom in Texas. Last year by this date, there were over 200 observations of this species in bloom in Texas. State-wide winter drought to blame? Fewer people observing this year?

The award this year goes to @ronstephens:

Gophers in the greater Houston area

Gophers are burrowing mammals that push up mounds of soil as they excavate. The current status of Baird's pocket gopher in the Gulf Coastal Plain of southeastern Texas (including the greater Houston area) is unclear. According to the Mammals of Texas, "Baird's pocket gopher has declined dramatically in the coastal prairies around the western edge of Galveston Bay. Land clearing and land subsidence have removed many of the low mounds characteristic of the coastal prairie at the turn of the century, and this gopher no longer occurs around Clear Creek and toward Houston."

However, there have been iNaturalist sightings of this species in the Houston area.

It would be a valuable contribution toward our understanding of this species if observers in the greater Houston area (including coastal counties from the Brazos river east) would keep an eye out for gopher mounds and document them.

One place I know they occur is adjacent to FM 2004 on the east side of Chocolate Bayou, near the INEOS plant (map). In the 1930's, gophers were documented on the north side of Texas City and just north of the Houston Space Center and along Clear Creek near League City--but they haven't been reported there since. They also should occur near Winnie and have been reported south of Anahuac (east of Trinity Bay).

Mole hills are often confused for gopher mounds, and I have some tips for distinguishing them. But observations of both are valuable. Post the pics regardless and we can identify them. If there are multiple mounds in a group, be sure to photograph the group as well as individual mounds. This helps confirm the ID.

If you know observers who might be interested in participating, please tag them here!
