It is time to go back to Palo Alto Battlefield National Historical Park (PAAL) again. But before I tell some of the great things that happened during the July trip I want to tell you a little about what happens in between the trips.
The journey between Lafayette, LA and Brownsville, TX takes approximately 9 to 10 hours each way. It is imperative that we make the money and time spent worth it. During the drive back, last time, William Finney, the network field biologist, and I spend a great amount of time talking about this project. You can’t imagine how much inspiration you can have when you are confine to a small space. The intention of this internship project is to implement, test, and evaluate the design of the radio tracking project which will continue beyond the summer. I can’t express how happy I’m to have the opportunity of giving my inputs to a project that will help improve the decisions made to manage the natural resources of one of our beautiful National Parks.
Between trips there is a lot of work to do, however when you know that what you do DOES make a difference and can have REAL impact on the results of science discoveries it is all worth. After processing our field data, pictures, GPS points, writing the trip report, and having project meetings we decided to modify the project design, and tracking procedures. I’m confident that the project changes will greatly improve the quality of this project results. So there you go, now that you know a little more what happens behind the scenes let’s talk about of highlights of this trip.
Contrary to popular belief tortoises do not walk super slowly. Here you can see one of our tracked animals in turbo mode.
Tortoises and snakes have the same hiding spots. This can be very dangerous if you are not extremely careful during you field work.
Tiny tortoises are adorable.
Doesn’t matter if you have a transmitter on you, there will always be a male that is attracted to you.
Contrary to the more common way of fishing ‘hook, line, sinker’, there is electro-fishing! Electro-fishing is a method used for scientific surveys of fish populations. Using direct current electricity you can create an electric field that stuns nearby fish. This makes it incredibly easy to net them. Once they’re netted you store them in the live well while you continue your survey, in which time they usually start to come back to normal.
When you’re finished collecting fish in your survey area then you can start to identify them. You keep track of the different types of species found and how many. Depending on the fish size, they may also be weighed and measured.
Knowing what types of fish are there and in what abundance really helps to inform you on water quality. Fish that are more reliant on clean water and are pollutant sensitive are a good sign. While having a profound amount of pollutant tolerant fish might mean higher pollution in the water.
These waterways are vital to the ecosystem, as are the fish that live in it, so these surveys really help to give us a good idea of the good and bad changes that’re happening in that environment.
