Accuracy, accuracy, accuracy is always good!

For any of the Texas Nature Trackers projects, accuracy is a very important parameter that determines the usefulness of an observation for inclusion in the Texas Natural Diversity Database. We encourage you to make sure you assign an accuracy of less than 500 meters when uploading observations. This is as easy as selecting on "location" and pinpointing your observation on the map and then selecting "update observation."

Curation Call for 2021 Data Pull

Greetings,

Texas Nature Trackers Biologist Craig Hensley has begun curating observations for this project. if you are a Curator/Manager for this project, you are encouraged to spend time curating over the next few months. Species of special interest to begin focusing on include Texas milkweed (A. texana), Emory milkweed (A. emoryi), slim milkweed (A. linearis), velvet-leaf milkweed (A. tomentosa), wheel milkweed (A. uncialis), Engelmann's milkweed (A. engelmannii), and slimleaf milkweed (A. stenophylla). Once these are curated, we can turn our attention to other species -- that said, any curation will be helpful.

Identification of Milkweeds in Texas - Revision

Identification of Milkweeds in Texas has been revised. The only change in content from the previous revision is the photos in the description of Asclepias emoryi. The previous photos were incorrect. It also has minor layout changes. There have been other revisions and corrections over the last two years. Revision numbers are not marked on the document so if you downloaded a copy it will not be clear which revision you have, except by comparing content.

The document location is https://tpwd.texas.gov/publications/pwdpubs/media/pwd_rp_w7000_1803.pdf

Unfortunately TPWD Creative & Interactive Services was, in my opinion, too aggressive with file size reduction by reducing the resolution and increasing the compression level of the photos. As a result the photo and map quality is well below that of earlier versions. I'm keeping my downloaded previous version for now.

The URL above should now be the only location for the document. Until recently at least one other location was active and contained a different revision. If you run across another URL location for this document on the TPWD web site or see a different URL given in a TPWD Publication, please report it to TPWD Creative Services. Or tell me and I will pass it along.

Texas Milkweeds Challenge: 1 down, 36 to go!

So far we have only documented one species, the Zizotes Milkweed. Kudos to @jsinghurst for being the first observer, and for @quintank and @skipkip for being early observers!

  1. Zizotes Milkweed by @jsinghurst on January 15th.
    2.......?

So 1 down and 36 to go! Can you be the first observer for a species of milkweed in 2017? Here is a live link to see the species that we have documented so far:

https://www.inaturalist.org/observations?captive=any&d1=2017-01-01&d2=2017-02-14&place_id=any&project_id=2990&subview=grid&verifiable=any&view=species

Remember that seasonality is really important, so early observations are really helpful. Here is the original post about the challenge:

Can you be the first? 2017 Milkweed Challenge!

Let's focus on phenology: "the study of cyclic and seasonal natural phenomena, especially in relation to climate and plant and animal life."

With Milkweeds, a big question is when and where they are available for Monarchs. To focus on phenology, we challenge you to be the first person to document a milkweed species in Texas in 2017. To get credit:

  • The plant must at least be vegetative, dead stalks don't count.
  • They observations must be added to the project.
    -The plant must be wild, pampered garden plants don't count.

So far no species had been documented! There are 37 species of Asclepias in Texas, so you have 37 ways to win!!

Here is a guide that might help: https://tpwd.texas.gov/huntwild/wild/wildlife_diversity/nongame/publications/media/tpwd-texas-milkweed-identification.pdf

Zizotes milkweed (Asclepias oenotheroides) still flourishing in south Texas

Zizotes milkweed (Asclepias oenotheroides) is still flourishing in south Texas on South Padre Island. Earlier this week while I was conducting botanical and plant ecology surveys at Brazos Island State Park in Cameron County, I encountered robust plants of zizotes in late flower, fruit, and seed dispersal. There were lots of Monarch’s visiting this milkweed and the many members of the sunflower family blooming along the lower cost of Texas. Although old man winter has arrived in the northern half of Texas, there are lots of native plants still flowering in the Coastal Bend and southern Texas. So if you happen to be along the middle or lower coast over the next month, keep and eye out for zizotes and make a milkweed observation or two. Happy Holidays!
