If you live in the US and experienced the wrath of the recent Polar Vortex, you undoubtedly have cabin fever. Big time. We all do! Just remember that even though it is the middle of winter, poison ivy, poison oak and poison sumac can still dish up a healthy dose of contact dermatitis and leave you very uncomfortable for weeks or longer if you don't catch it in time. Be on the lookout for white berries on stems with an alternate leaf arrangement (leaf scars are not right across from each other). The stems with berries are the female plants and many of the berries are still present on the plants throughout the winter and spring.
Remember to wash your clothes as soon as you get home from your much-needed nature fix, since you can get urushiol oil on your pants or snow pants. The oil will linger on your clothes while sitting in your laundry basket and spread to other articles of clothing, yourself or a family member. Also wash with Dawn dish detergent immediately if you think any part of your skin came in contact with one of these rash plants.
Enjoy your hike and be safe!

In a shocking (and awesome) announcement by the Monarch Joint Venture (MJV), eastern monarch populations are up 144% from last year!
If you recently read that monarch populations are down a devastating 86% this year and now you're hearing they are up 144%, don't worry, you aren't losing your mind. If you are unfamiliar with North America's monarch butterfly populations, it's important to note that there are two separate migrating populations in the United States and one mostly nonmigratory population in Florida.
The two distinct migrating populations include one in the far west (west of the Rocky Mountains), and one in the east (east of the Rocky Mountains).
We'll start with the bad news first...
Western Population: This is the population that has declined 86% this year, which couldn't be worse news for an already struggling population.
(Read Naturedigger's earlier blog posts to find out how you can help)
Where do they migrate to and from? The western population overwinters along the coast of California and migrates in early spring to the Rocky mountains, then returns to the California coast in the fall. See the migration map below provided by Monarch Watch.
Now for the good news...
Eastern Population: This is the population that is rebounding (at least this season) and appear regularly in the news due to their dramatic decline over the last 20 years.
Where do they migrate to and from? The eastern population overwinters in Mexico, specifically in the in the oyamel fir forest, which is how the population numbers for the year are determined. In the spring they migrate north from Mexico and fly throughout the United states east of the Rocky Mountains, north toward Canada and east throughout the eastern United States. The last generation then returns back to their wintering grounds in Mexico in the fall. This epic migration is as mysterious as it is truly remarkable.
See the map below provided by Monarch Watch and the chart of population by hectare in Mexico provided by the Monarch Joint Venture.
So what can we attribute this unbelievable increase in eastern monarch populations to? According to the MJV, "Good weather conditions during the breeding season supported the increase, as well as efforts across North America to protect and restore habitats."
The weather is something we obviously have no control over, however, participation in habitat restoration we can all control. Clearly the formula the MJV (and its many partners) is using is working.
Now let's get to work on the western population and see if we can bring those numbers up next year, as well.
Check out the MJV's website links for general information about monarch nectar plants and much more as well as specific information about the eastern migratory population. Visit the Xerces Society for guidance on the western monarch population as well as pollinator plants for your area if you live in the western US.
The Xerces Society Thanksgiving count numbers were just finalized for our North American western monarch population and it's as bad as the initial estimate. According Xerces, we have lost 86% of monarchs within the last year, and they have issued a call to action. This is serious.

If you're a news junkie like most of us living the United States have become, you've undoubtedly run across the numerous articles about the dramatic decrease in our western monarch population in 2018. Our MJV partner, Xerces Society, who conducts the annual Thanksgiving count, released preliminary overwintering monarch numbers in an alarming statement this week which should cause concern among not only the western states where this is occurring, but everywhere, since this unprecedented decline is likely caused by several factors that affect everyone. Below is an excerpt:
"Pesticides, habitat losses and more frequent and severe droughts caused by climate change are believed to be the primary reasons for the decimation of the butterfly population," Xerces says.
Take moment to read the article in its entirety and comment below.
We can all make small changes in our lives such as planting only native plants and not using pesticides in our gardens or on our lawns. Conserving open space in our communities needs to be a top priority or we stand to lose this iconic species and many other beneficial pollinators along with it.
Get off the couch and head outside this holiday season! Nature calms the nerves, soothes the soul and fills the heart. You may even find a little humor in it along the way!
Knotweed! has been updated with new slides, seasonal photos and information. It is now compatible with iOS 12.0. Below is a sample slide illustrating Japanese knotweed's ability to do serious property damage. Check out more of our slides for each knotweed species in the Quick ID section under each species in the app. Also visit the knotweed page for similar information. New seasonal photos and descriptions will help you ID all species of knotweed throughout the seasons. Can you identify Japanese knotweed along the highway right now? The canes are typically reddish at this stage and very easy to spot. See the photo below and download knotweed! for more information.
