Tick, tick, tick….
The recent refreshing rain likely to have rejuvenated more than just our local waterways:
“…for someone hiking, ticks will have gone from practically zero a couple of weeks ago to being out…and their numbers will probably be increasing through January.”
A few tips from the American Hiking Society:
- Determine risk: Spring and early summer are high-risk for ticks because ticks are in an earlier stage of their development, called “nymphs.” Nymphs often carry heavier loads of disease-causing pathogens, and are smaller and harder to spot. Tall grass and brush are higher-risk, too, because ticks can easily climb on to hikers.
- Wear long and wear light! Wear long-sleeve shirts and long pants of a light color. Lighter colors seem to attract fewer ticks and make the ones that do end up on you easier to spot. Lightweight nylon or polyester garments are almost as cool as shorts and protect from the sun as a bonus!
- Seal the cracks. Tuck your shirt into your pants and tuck your pants into your socks. Gaiters can add an additional level of protection and keep small rocks and dirt out of your shoes too.
- Repel invaders! Consider treating your clothing with a persistent repellent chemical called permethrin. This substance, applied to clothing, repels ticks and biting insects for up to 2 weeks. Some clothing comes already coated with this deterrent. Apply an additional repellent to all exposed skin.
- Wash your hiking clothes. As soon as you get off the trail, wash your hiking clothes and dry them in a hot dryer for an hour. The heat will kill any ticks.
- Tick check. Showering within two hours of leaving the trail will help wash off any ticks which haven’t latched on. Using a hand-held or full length mirror, take this time to check yourself for ticks, especially checking armpits, hair, ears and behind the ears, belly button, behind the knees, and groin. Be sure to also thoroughly check your children and pets.
- Remove any ticks. If you do happen to find a tick on yourself, do not use the old trick of poking the tick with a hot match head until it comes out. Do use tweezers and grab the tick as close to the skin as possible and slowly pull it out. If you can’t grab the head in the first go, make sure to pull it out before washing the bite with a disinfectant. View the CDC’s easy-to-follow tick removal instructions and pictures.
- Stay vigilant. If you develop a fever, rash, muscle and/or joint aches, flu-like symptoms or become ill, be sure to mention to your doctor possible tick exposure. Lyme disease is very serious and can cause permanent damage in bones and the nervous system. Tick bites that develop a bulls-eye ring are infected and should be treated immediately.
If you find that you have been bitten by a tick, save the insect after removal and submit it to Sonoma County Department of Public Health for Lyme testing:

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.
