Tick Season is Here!

This week I found the first tick of the season crawling up my pants. In my experience, ticks are more prevalent in the wet period of winter and spring than they are in summer. Therefore, you will need to be vigilant for ticks for the next several months at least.

And being vigilant can be hard, as they can be quite small (see picture). When you’re inspecting yourself, look for any small dark dot. It’s good to look over yourself and your companions once you’ve left the trail. Even better, take a shower after your hike, so you can do a thorough body check. Try not to brush against trail vegetation, as they like to sit on the ends of grasses to get on you as you brush by.

Finally, if you do get bitten, extract the tick carefully with tweezers, put it in a small ziploc bag with a moistened cotton ball and send it in to have it tested for Lyme disease. I did this twice last year and thankfully neither tick had the disease. However, I tend to have a serious reaction to the tick bite if it has been in me for longer than an hour or so, which includes pain, itching, swelling, and a temporary scar at the bite site (which can last for months).

So by far, the best strategy is to prevent yourself from getting bitten in the first place. Stay safe out there!

Why We Fight

I’ve posted a lot about invasive species removal from the Overlook and Montini Preserve properties. Anyone but me would likely say too much, and who could blame them? Not me.

But in reviewing what I’ve written over the years about it, I realized I’ve never explained why we fight this fight. So now I rush to make good this oversight, and try to explain why I go out, nearly every day I can from January through July or beyond, and fight something that will very likely never be defeated.

First and foremost, it’s necessary to highlight the fact that species such as Italian and yellow star thistle will completely take over an ecosystem. You don’t need to go far to see this happening. The picture here was taken at the Sonoma Valley Regional Park, and shows how Yellow star thistle in the foreground, and Italian thistle in the background, have essentially taken over a meadow. This crowds out native plant species and even mammals.

Thistle creates a “no-go” area for wildlife, who avoid such patches until they can’t be avoided at all, and then they move elsewhere. This of course leads to a an ever-increasing monoculture and “dead zone” where only the invasive species thrive. “Invasive species are among the leading threats to native wildlife,” states the National Wildlife Federation, “Approximately 42 percent of threatened or endangered species are at risk due to invasive species.” This is clearly a serious threat that must be addressed.

The impacts of this monoculture are many. Wildlife doesn’t have the food sources they should. The lack of diversity in plant life affects the diversity of everything else — insects, reptiles, birds, and mammals.

Invasive species can also affect the chemistry of the soil, as well as the intensity of wildfires.

There are, then, many reasons why we fight this fight.

Recently as I walked along the main path in the Sonoma Valley Regional Park, I was in despair seeing the extent of Italian and Yellow star thistle invasion. It was heartbreaking to see. But I had to turn away, knowing that I have my own battle to fight on the Overlook and Montini Preserve properties. Thankfully, the Yellow star thistle is nearly eradicated on those properties except right along, and next to, Norrbom Road. But we have a long, long way to go against the Italian thistle, let alone Scotch and/or French broom and other invasive species that we have yet to assess, let alone seriously address.

In the end, we fight this fight because the alternative is so much worse. We fight because we love the native ecosystem and we believe deeply in saving it. We fight because we have no choice but to do so, loving these properties and trails as we do. Frankly, that’s the absolute best reason ever to fight for something — for love. So if you see me or my comrades out there, with a large bag and a glove, you’ll know what we are doing. We are fighting for something we love.

That’s why we fight.

Oh, Spring!

Spring is the season of renewal, which manifests itself out in the wild in a myriad of interesting and beautiful ways. Certainly the abundance of wildflowers is an obvious example of spring, but it’s by no means the only sign. In certain areas of the state, we were blessed with a “super bloom” of rather massive proportions that was truly something to see. Entire hillsides were painted with orange, or purple, or blue wildflowers. I was in the Merced River canyon just outside Yosemite in April and you could look up and see an entire hillside of California poppies. So…yeah, wildflowers are, I assert, one of the most beloved signs of spring.

But of course there are others.

Once the Western fence lizard makes an appearance, you know spring has sprung. These reptiles need warmth to be able to move around, so once the weather gets warmer they will be seen on the trail. They are definitely our friends in a particular way. “Studies have shown,” Wikipedia tells us, “Lyme disease is lower in areas where the lizards occur. When ticks carrying Lyme disease feed on these lizards’ blood (which they commonly do, especially around their ears), a protein in the lizard’s blood kills the bacterium in the tick that causes Lyme disease.” And since another sign of spring is the presence of ticks, the timing is fortunate.

Other reptiles such as snakes are frequently spotted in spring, as they are out and about looking for a mate. Many mammals are as well. Just today on the Montini Preserve I saw a male wild turkey in full display, trying to attract a mate from a bevy of females (see picture, the females were out of the frame). A couple females were fighting, I presume over the right to go after this fine specimen. Oh how I wish females would fight over me, but then I’m not nearly as good looking as a turkey. Sigh…

 

Tick Season is Here

Yesterday, after pulling invasive weeds on the Overlook Trail, I found a tick lodged in the inside of my arm. So today, as soon as I got home from my session of weed pulling, I stripped and inspected myself before heading to the shower. I was shocked to find that another was attached to my side. It had apparently bit me before I even had a chance to find it. I was out for about an hour-and-a-half. Luckily, I hadn’t yet mailed my envelope to the Sonoma County Department of Health Services to test the first tick for Lyme disease, so I added it to the envelope and doubled the check (they charge $33 to test a tick).

Part of the problem is that these buggers are quite small (see the picture of my first tick). That means when scanning for a tick on your clothing or body, you need to look for a very small, essentially black dot. Also, my work takes me off the trail into the vegetation, which most hikers and runners have no need to do (so my story isn’t necessarily indicative of the actual danger).

In a weird confluence of events, I found the first tick while in the quarterly meeting of the Sonoma Overlook Trail Stewards. I discovered that my arm was sore, and I couldn’t figure out why that would be, so I looked at it, and found the tick. Thankfully I never go anywhere without my Swiss Army knife, so I ducked out of the meeting and extracted it with the tweezers. I wrapped it in a tissue for safe keeping.

To prevent your own up-close-and-personal encounters with ticks (which is really the purpose of this post), I suggest doing the following:

  • Avoid touching or brushing against vegetation.
  • Inspect yourself and others for small black dots.
  • Tuck pants legs into your socks.
  • Shower after your hike.

I made a couple signs to this effect to put at the entrances to the Overlook, and will make another two for posting on the Montini. In my ignorance, I hadn’t realized that ticks would be out by now. Richard Dale, of the Sonoma Ecology Center, told me at the Stewards meeting that they have been out for a couple of weeks. In the future, I hope to be better about warning people of the danger as soon as it becomes real. Even I could have used the warning. Stay safe out there, hikers and runners!
