We all took a break before we finished this part of the ranch.

It looks like we will be at the Haggard Ranch longer than we expected. We found more thickets of tallows, so the work continues. We are making progress and see more “friendly” trees. It’s encouraging and fun to explore the ranch.

We continue working at the Haggard Ranch. We think we are near the end, but we always find more tallows and the regrowth is terrible. We are lucky to see the many changes in the ranch where nature is the best. Today we saw lots of cactus tunas and river h**p.

We returned to the ranch after the massive rains last week. We continue working in the same area. Today was the first day for 100 degree temps. We are slower and take more breaks, but we continue working on the tallows….we just socialize more. We love what we do.

We returned to the ranch today. As we usually do, we split up into two groups. We continue working in the same general area and are making progress, but there is still work to be done. We even took down a chinaberry tree along with the many tallows. We will return to that area next week.

It was a hot and humid day today at the ranch. We still worked on removing Chinese tallows, but we took lots of breaks and quit early. In addition to the tallows, there were lots and lots of cockleburs. They are no fun and bad for the cattle.

It was a special Saturday workday at Woodland Church. The property was very cool, but it did have lots of invasives. We found nandina, confetti lantana, ligustrum, chinaberry, primrose jasmine, johnson grass and Chinese pistache (all invasives). We also saw the biggest mustang grape vine ever (a great native plant). As usual, we also found some cool stuff like pearl milkweed and deer antlers. We also removed quite a bit of trash. We did not finish the area and will have to return on a different day. However, we got a good start.
