How to use this site

Hover the mouse over terms to get more information. It may be necessary to click the term if using a mobile device. Notice how the term is underlined. Any word in white text and underlined in yellow is a term. If a popup does not disappear automatically, click on it to close it.

Enter text in the search box and hit the ENTER key to search within common names and scientific names. Not all content on the site is searchable.

Click a photo to see a larger version. Use arrow keys to go through other photos from the same page. Hit the ESCAPE key to return to the page.

Hover over photos or breadcrumbs to see tool tips.

Any lengthy topics are placed at the bottom of pages. This information is not repeated, but will be located on the first relevant page. For example, to review general information on flowers, look at the botton of the Flowering Plants page, and to review general information on leaves, look at the bottom of the Plants page.


How complete is the content?

Some areas are more complete than others. There are three ways in which the list of species may not perfectly match reality.
  1. Not all species listed.
  2. Extra species listed.
  3. Wrong species name provided.
The mostly likely case for any given subset of the site is that not all species are listed. Some popular topics, like birds, butterflies, or trees, are more likely than others to be complete. It is important to have an idea of how comprehensive a checklist is so that you know how likely it is that your observed specimen is on the list. Pay attention to the resources that are used for evidence. If the resources are likely to be comprehensive (such as the Texas Bird Records Committee), then the list here is also likely to be so. If the evidence relies solely on casual observations, like iNaturalist or BugGuide, then it is more likely that not all species are listed on Texas Nature.

A species could be listed that does not really appear here if it was incorrectly identified in the source material. This is more likely to happen where the evidence is taken from a resource that includes amateur input, including my own observations. The source of evidence is always noted, and you can make your own judgement as to the reliability of the input. Extra species could also be included if the evidence is taken from a range map and not from a specific sighting. This is because a species range may cover a certain area, but the species might not be found in a particular part of that range if its favored environment does not exist (such as wetlands). I am avoiding range maps for Texas state records, but they might be used for counties later. It is also possible that an entry might be just plain wrong. Hopefully this is rare.

Lastly it is possible that an organism does belong here, but the wrong scientific name is given. It could that there were taxonomic changes such as a species split, and only the new species resides here. Perhaps the genus was changed based on new research, and not yet reflected on this site. Sometimes a scientific name is updated only to correct the Latin suffix.
