Look for Silver Linings: Go Hike and Seek

By Beth Sullivan
Even in the middle of a crisis, some things remain unchanged. What a difference in our outlook from a couple of weeks ago. At this point, there is no use in discussing how we got to this point in this public health crisis. But we can do our best to stay informed, take precautions seriously, and try to maintain as much normalcy as we possibly can, as a community and as individuals.
There are certainly things that are so totally impacted, that there is no way to avoid the consequences. Kids are out of school. Period. It is not like a vacation or summer break that was planned for. It is not like a snow day that was unplanned, but where playdates and special programs could keep groups of kids entertained and safe. Parents are home because their jobs disappeared, or because they don’t have child care. Maybe they are lucky and can actually work from home, if the kids will let them.
But here’s the good news, and we are all looking for that. We are heading into spring. We have really been lucky with good weather getting to this date and even if we get a late snow storm, we get over it quickly. Get those kids outside. Obviously, if they are ill, they need special attention, but getting them out into the air, roaming, running , being creative is one way to keep them engaged and happy as well as healthy.

As we go through the flowering season, you can draw them, even dissect them. Get out the books to help.

Millipedes are easily found under leaves. They do not hurt. Check out those legs.

Be a teacher

Think of what great lessons, you, as an adult, can teach them about the new season. It is an opportunity to observe daily changes. Even the youngest ones can appreciate a new flower, or something getting bigger. Look for acorn caps; touch the moss. Let them pick a flower and then show them that you cherish it. Make it important. Slightly older children can do some drawing. Test their observation skills at their appropriate age level. Discuss color, texture, and comparative sizes. If they are ready to write, get them to use descriptive words. You can discuss weather conditions and keep a journal. Have them observe the sky, clouds, feeling of the ground, wet or dry.
Look at the differences in several kinds of plants. Are their stems hard or soft? Watch the changes in their leaf development. Pull a dandelion out of the ground and look at the roots. You probably don’t have to go very far to find a shrub with some buds already showing. Forsythia is everywhere. Before you know it, both of you will have become better botanists.
Then there are insects to watch for. Look under rocks and logs. Lift piles of leaves and see what’s under there. At this point in the year, there are already insects and their relatives, moving around. There are also amphibians to look for, and listen for. There are probably salamanders under those leaves. You can find a small wetland near your home and listen in the afternoon or early evening for frogs. Peepers and wood frogs are chorusing now.
And of course there are the birds. Spring is meant for birdsong. Kids never really like to sleep in, unless they are teenagers. Get up and sit outside on a nice morning and listen to the birds. Can you find them? Can your child describe them for you? Take notes together. Draw pictures.
This could also be the time to let them engage with a smart phone a bit more. There are so many wonderful apps available now that help you identify all sorts of wildlife, birds and their songs, and all aspects of plants. There are still amazing books.
No spring excursion is complete without checking out the skunk cabbage.  Watch as the plant changes through the season. 

Textures on tree bark can make great rubbings or abstract photos.

Trees have lovely flowers if you can look closely These are red maple.

Check out Avalonia’s Hike and Seek program

 Not every adult is really comfortable with all I have just suggested. Some people really want a guide. That’s what Hike and Seek is like. As a parent, take some time to review it. Find a preserve near you. Look at the preserve pages, maps and photos that are targets and clues. There is also a Resources section that allows you or your young student to look a bit deeper into a subject. It is all accessible on your smart phone. Take it with you on a hike. Take photos and write stories. Do it together. The trails are not crowded. The air is clean. It is almost spring. It is the very best way to stay physically and mentally healthy at a time of social distancing and isolation. Earth-Dirt doesn’t require sanitizer. Use this time with the child in your life, in a positive way and help them learn to look for that silver lining. It is a great de-stressor for grown-ups too.
We caught two wood frogs and a peeper recently. Keep them moist, observe them, then let them go.

Migrations and change

By Beth Sullivan
There is something about March that always makes me think of change. Looking back over all the years of writing this blog, there always seems to be one dedicated to this topic in March. Of course it is the transition time between seasons, and for many of us, it is a very welcome transition in both temperature and light.
Swallows stage magnificent migrations in the fall.

It is a time of migration

Migration is defined as passing periodically from one region or climate to another. It is also defined as shifting: as from one system or mode to another. We think of the great migrations of large mammals on the plains of Africa. Locally, migration can be a bit more subtle, less earth shaking. In the fall, in particular, the movements can be quite large and impressive, as birds flock and prepare to go south. We have witnessed the magical formations of swallow species as they come to roost at night, in preparation for migration south. School children learn early about the migration of the Monarch butterflies from their northern birth places to the forest groves in Mexico.
The return migration, coming home here, or leaving here for more northern lands, is generally more gradual. There have been reports of large flocks of songbirds making their way north already, in masses so large they show up on radar. Scientists have said it is weeks early. By the time they arrive here, their numbers have scattered, and they are less impressive in their presence. We have to hope that their return here, possibly too early, will coincide properly with emergence of enough insects to fuel them.
These are annual, seasonal migrations. But there are other, more subtle ones. Only a half century ago, there were no red bellied woodpeckers in Connecticut. They were southern species that are now common at our feeders. Other familiar birds, like titmice and cardinals have moved slowly north over the last centuries to set up year round residence. Now they are our familiar favorites. This didn’t happen in one season, or one year, but very slowly as these species moved north where they found adequate food and habitat. In some cases they created a new niche for themselves. In others, they shared resources and even competed with those species that were here before them. The southern birds were not invasive; they were, technically native, just on the move, expanding their range.
But here’s a new one, one that you may not have thought about: plant migration, particularly trees. Obviously trees can’t get up and move when the weather changes; they don’t rely on seasonal food sources, and they need to tolerate and even adapt to sometimes extreme changes. If they can’t adapt, they will die. With the climate changing - warmer overall, less snow cover, periods of heavy rain yet drought in summer, as well as severe weather events the tree species are challenged to adapt quickly. In addition, invasive insects and new diseases are attacking our native tree species with frightening strength and frequency. Warmer winters have allowed these diseases and pests to survive. Chestnuts were among the first to go, over a century ago; then the elms. Beech trees are stricken by bark blight diseases. Birch trees have cankers. Our hemlocks are doomed by the woolly adelgid. Ash trees are being destroyed by the emerald ash borer. White pines are not surviving to maturity due to disease, insects, and the heavy wind events destroying and toppling them. Our mighty oaks cannot tolerate the years of defoliation by caterpillars, combined with summer drought and saturated soils smothering the roots during wet winters.

Fifty years ago there were no red-bellied woodpeckers in Connecticut.

Assisted migration

When openings in the forest are created, either man made or nature made, what fills back in are often the same species from seeds that have been in the soil. They will be faced by the same challenges.
Scientists studying this issue are beginning to think of a concept called assisted migration. Trees can’t move far or fast on their own, like birds can. It takes centuries for plant species to expand their range northward as conditions change. One approach is the idea of assisting nature, by bringing north tree species that are native to areas just south of here, species that are adapted to conditions that we are now experiencing. There are oaks and pines that can occupy the same niches as our historically native ones do. Wildlife can make use of these more similar native species, much better than they can non-native species from other countries. Southern natives are less likely to ever become invasive.
We have a number of tree species that are present now, at the northern limit of their range, such as the tulip tree and tupelo (Black gum), and as climate warms they will be tolerant and spread. But we can make it happen faster by using such species to fill in openings and clearing.
As we begin our planning for the restoration of the forest at the Hoffman Preserve, we are beginning to research mid-Atlantic species that may grow and adapt and help create a forest that will last through the next century of change. It is very interesting and hopeful. Stay tuned.
Our mighty oaks and hemlocks are stressed and will not survive the warming climate.

The tulip poplar tree is present in southeast Connecticut but is also tolerant of more southern conditions.
