An Autumn Tree Observation Extraordinaire

We decided that our autumn study of leaves was going to be incorporated into our annual fall trip to see the colors of the aspens up in the high country of the Sierra Nevada. The trip is about 100 miles round trip from our front door but it goes through magnificent forests, by snow fed lakes, and in view of some of the most breathtaking mountains in existence.

The first leg of the trip goes through the pine forests and we thought our day had come to an end before it really started when we encountered a control burn of the forest floor by the US Forest Service. They clean out the underbrush by setting fires and then controlling the burns. It makes a lot of smoke but we were able to drive down the highway and past the fires onto our destination.

The second part of the forest is actually in Alpine County and the forests are mixed in with aspen groves to make wonderful color in the fall. You know the minute you hit this part of the habitat because you start to see the yellows, oranges, and golds of the leaves.

We have a favorite side road that has the prettiest meadow. Yes, that is my son out there taking just as many photos as I am on this day….it is awesome to share a hobby with your grown up kids.

Here you can see the shape of the aspen leaf and the trunk of the tree in all its beauty. I never tire of looking at aspens.

It was fairly cloudy this afternoon but for a few minutes the clouds parted and we had a chance to capture the blue sky in contrast to the bright yellow leaves.

We drove the next leg of the road which leads through a place called Hope Valley. This is “the” place to see fall color in our area. There were many of us lined up on the side of the road to capture the oranges and yellows and golds of the trees on the mountain. Isn’t it dreamy?

Then as we headed back around to Christmas Valley, we saw this scene. There were some people on horses rounding up a herd of cattle. Stop the car! Yes, we had to take a few photos of this and it was the perfect way to end up this part of drive.

We observed some of the leaves “quaking”. We learned from our field guide that the reason they shake that way is because the stem is flattened near the leaf and so when the wind blows they shake or quake. It sounds sort of like the ocean to me when you hear them quaking and is a nice sound. Here is a link to try: USDA Quaking Aspens.

There was more to this trip but I will save that for another post. We actually went to see the salmon spawning and there were quite a few ducks to observe as well. Stay tuned for a salmon post when that challenge comes up in a few weeks.

I also am going to post a separate entry for our leaf comparisons since this post became rather long. Stay tuned for part two. We also have picked a new tree in our backyard to observe for a year-long tree study and I will share our fall observations with the leaf post.

Today we will be working on the apple challenge but the horse challenge is still in the works.

Winter Tree Study: Tuliptree

We completed our Winter Tree Study a few days ago before all the rains started. Last fall we chose our Tulip tree or Tulip Poplar to observe in every season for the next year. It is the tallest tree in our front yard. It lost quite a few branches during our December snowstorm so it has a little different shape than it did back in October.

There are virtually no leaves left on the tree at this point.

The boys noted that there are still a million helicopter type seeds left on the tree.

The ground under the tree is covered in seeds. The boys are going to sketch some of the seeds into their nature journals.

Mr. A wanted me to note that he had to spend the better part of an afternoon last week cleaning out the rain gutters and downspouts and the bulk of the mess was from this tree with its helicopter seeds. They are just thin enough to sift through the screens over the rain gutter.

Here is a small cluster of the seeds on the ground under the tree. We noted they look like wooden flowers.

The most interesting part of our winter tree study is the moss and lichen growing on the trunk. It is really noticeable now that the tree is bare. We took a few minutes to observe the moss. Words like soft, fluffy, bright green, and spongy were used to describe the moss. It is most definitely more prominent in the winter and far greener than the fall.

Here is a link to our Fall Tree Study so we can compare the two seasons. What a difference! Now we will wait until spring to make our official study of the changes in this great tree in our yard.

As a sidenote…

Here is something that made me smile. Look at those bulbs peeking out of the ground already! I know that underneath the ground there are dozens and dozens of bulbs just waiting to pop out in flowers before long now.

Hope you get to your Winter Tree Study soon.

Family Outdoor Hour: Nothing Like an Oak

My oldest son and I had the opportunity to take a long walk together and enjoy the oaks and pines along the walking trail. He has such long legs that he ends up way in front of me most of the time but that gives me a chance to snap a few photos as we walk. He stops every now and then to let me catch up…..yep, I feel like an old lady.

Oaks make me happy. I love the variety of oaks with their different shapes and here in California we have quite a few to study. Last year we kept track of a Live Oak growing in our backyard. We also have quite a few scrub oaks in the back of our property.Here is a previous post on our oaks: Oak Challenge Entry

There is nothing like the smell of warm oak leaves in the sun.

Oak galls fascinate me and the boys think they are pretty interesting as well. Oak galls are basically abnormalities on plants caused by insects. We noticed that there are not as many as usual this autumn and we wonder what that means.

I love the shape of oak trees and this one at my dad’s house is a big old oak. I took an informal poll of my three boys and asked them which they preferred: oaks or pines? Two oaks and one pine…..I think if I had to make a quick answer without thinking too much I would pick oaks as well.

We have noticed how different the acorns are from different kinds of oaks.

We had a wet morning to observe the oaks in our backyard but I really like the way the wetness brought out the texture in the bark.

Here are leaves from one of our oaks. We are assuming the red parts are the new growth. We will have to keep checking to see if we are right.

I really like using the Peterson Field Guide-Western Trees book for our tree identification. The color plates show the leaves, the buds, and the acorns. Once you get an idea of which oak you think you have, there is a reference to a page number to read the narrative account along with a photo and range map. You can find the tree guide listed on the Autumn Series Squidoo lens (scroll down to the additional resources section).

We made leaf prints last week with our oak leaves and they are included in our nature journals for this challenge.

These challenges are helping us stay motivated to get outdoors which is always a good thing.

Our Tree: Tuliptree or Tulip Poplar

Trees are such a part of our life and there are quite a few growing in our yard that delight us during the different seasons. In the past, we chose an oak and then the sweet gum tree to study for a complete year.

We talked it over and decided that our new year-long tree study as part of the Outdoor Hour Challenges will focus on a Tuliptree in our front yard. I was leaning more towards studying the Chinese pistache that is actually in our neighbor’s yard but so close to the fence line that it might as well be in our yard.

The boys campaigned for the Tulip tree and since the whole point is to get them enthusiastic about a tree, we will go with their choice. The photo above shows the top of the tuliptree and to the right of it is our magnolia. The tuliptree is much taller than any other tree in the front yard and gives us lots of shade in the summer.

We talked about the tree for a few minutes before we headed out the door to spend our Outdoor Hour Challenge time observing our new tree friend. We talked about how the robins like to sing from the top of the tree, how the seeds are like helicopters, and how tall the tree is growing. One son added that he likes the tree but it is one of the biggest producers of leaves and soon it will mean lots of raking and composting. I shared how I remembered the blossoms on the tree and the humming of the bees last spring. We already knew quite a bit about our tree so we were anxious to see if we could learn anything new.

We took photos of our Tulip tree and gathered a few leaves to put into the flower press. A journal entry was made so we can compare with our winter study.

Most of the leaves are shaped like this……

But there were some that were shaped like this……

We were wondering why the leaves on the same tree are shaped so differently…..any guesses?

Many of the leaves have fallen already and there are quite a few turning yellow-orange-brown as well.

This is the fruit that turns to the seeds….great helicopter seeds that fall by the thousands.

How about that bark? It has the fluffy green lichen and the flat bright orange lichen as well.

We actually had a squirrel friend spend some time in our tree this afternoon.

This was a great start to our new tree study and this tree will be easy to keep track of since I can see it from my bedroom window. I love watching the shadows of the branches and leaves on the blinds. It makes a great swishing sound in the summer when the breeze blows and during winter storms it has a sway and a creaking sound as it bends in the wind.

We will try to spend some time this week watching as the leaves start to really fall and before you know it, this tree will be bare. 🙂

Climbing Trees-No Weather to Speak Of

Still no “weather” to report from our house. The windows and doors are still wide open and the sky is clear. We have forecasts of some rain maybe this week so we are going to wait until then to take a weather study.

In the meantime, the boys and their father decided today was the day to climb a tree. We have one really big tree in our yard that is fairly easy to climb because the limbs are close together and there are so many of them. They took a ladder to get started but then climbed up from there.

This was the first time that I have noticed cones on the ground under this tree.

I grabbed the tree identification book and here is what we came up with.

Here is what we used to identify the tree….leaflet and cone.

It looks as if we have a Giant Sequoia in our backyard, right next to our deck.

This is my best attempt to take a complete photo of the tree showing our deck at the bottom. It is a really tall tree.

“The seed cones are 4-7 cm long and mature in 18-20 months, though they typically remain green and closed for up to 20 years; each cone has 30-50 spirally arranged scales, with several seeds on each scale giving an average of 230 seeds per cone.” and “Young trees start to bear cones at the age of 12 years.”
Wikipedia on the Sequoia

So what started out as tree climbing ended up with identifying our very own Giant Sequoia in our backyard. It was growing here when we moved in 21 years ago and I assume it was planted by the previous owner. It does provide great shade on our deck during the hot summer afternoons and the birds and our backyard squirrel like to use it for protection.

This tree has been hit by lightning once a long time ago in a really big storm. It sounded like something exploded in our backyard during the thunder storm and we went outside to see what it was and we saw a long black line on the trunk of the tree and it was smoking at the base. It was very memorable.

What an afternoon.

English Walnuts-Yes, Another Tree Study

Today was *another* cloudless day but we were outside looking to see what we could find interesting in the backyard. The walnut tree now that it has just about lost all of its leaves was our subject of the day. First we started looking at the way the woodpeckers have over the years made numerous holes in the trunk and large branches. Be sure to click the photo to get a better look.

As we examined the trunk closer, we noticed the change in the texture of the bark shown in the photo below.

I was interested in what was going on with it and I somewhere in my memory have stored away that my husband had once told me that they graft the English walnut onto the black walnut tree because the black walnut is a native of California so it is a hardy tree, resistant to pests but the English walnut has a thinner shell and easier to open and eat.

We decided to ask him more about it and to look it up on the internet once we got inside from our outdoor break.

Here is what we found:

Did you know that California grows 99% of the United States’ walnuts?
That is an average of 303,000 tons of walnuts every year!
The Romans called the walnut Juglans regia or Jupiter’s royal acorn.
My husband was absolutely correct and the English walnut is grafted onto a black walnut rootstock.

Fascinating! I have never noticed the grafting before in all the twenty plus years we have lived in this same house. If you want to know more about the California(English) walnut here is a link to a simple to read explanation. California Walnut

Here is the pile of leaves under the walnut tree. So many leaves to rake but not many nuts due to the resident squirrel and the Scrub jays.

Various Tree Musings

I realized as the weekend went by that I have started noticing tree trunks and how they are all so different. Someone mentioned this in a post and if I remember who it was, I will link to her. She was talking about how she wonders why we always color a tree trunk and branches brown when they are nearly all some other color. I thought this was interesting and ever since reading her thoughts I have been fascinated by the different colors and textures of tree trunks.

Magnolia trunk

Birch trunk

Oak trunk

Our trip to Oregon gave us some good tree memories. Here are a couple of photos and thoughts to go along with them.

Here is one of the tallest trees in the world, if not the tallest. Apparently, the tallest tree changes from time to time and I couldn’t find any solid evidence online to point to this particular tree but we will just say it is one of the top ten tallest trees in the world. Most of the tallest trees are found in Northern California among the redwoods. (Giant sequoias have more mass but are not taller.) I enjoyed the tree no matter how tall it was and just standing at its base, I was humbled. My thoughts turned to how long it has been growing and all the things that have changed in the world since it was a seedling.

This beautiful madrone tree in Oregon caught my eye. I wish now that I had taken a few extra steps to really examine and photograph the color of its bark in light of my current thoughts on trunk colors.

How about this beauty of an oak along the Rogue River in Oregon? It was just perfect for gathering acorns under and for a little shade on a warm autumn day. There were plenty of blackberries still waiting to be picked along this trail as well. We took a long walk along the river and enjoyed the solitude.

As we wind up our study of trees in the next few weeks, I am going to try to focus on the changing of the landscape due to the falling of leaves. I did notice this morning that the weekend’s rainstorm had hastened the falling of many leaves. I have a better view across our little valley and can see more clearly the neighborhood because the view is not obstructed by so many leaves. It is a different landscape…changing but still pretty.

Trees seem to frame my life.

My boys have become more aware of trees these past eight weeks. Having a focus draws attention to a certain aspect of something that we see every day. My middle son takes his dog for a walk each morning and each morning he finds a special leaf to bring to me as I cook breakfast. He always has an explanation for why he picked the leaf and then lays it on the table at my spot for me to enjoy. Something so simple but it has touched me that a fifteen year old boy takes the time to focus his eyes at least for a few minutes each day on something most of us don’t take the time to notice and then make it special for his tree lovin’ mama.

I find myself feeling grateful for these little gifts that nature study has brought into our family’s life.

Outdoor Hour Challenge #20 Our Summer Tree Study

We have had hot smoky weather for the past two weeks with all the fires burning in our area. It is very unusual for the wildfires to start so early but my husband says that the fuel in the forests is so dry that it doesn’t take much to get it going. We had several dry lightning storms and two weeks ago we had extremely high winds. All these factors together make for extreme fire danger.

We have been enjoying our outdoor time both in the garden and out on hikes in our local area. First of all though, here is my son’s summer tree study.His tree doesn’t look that much different from our last study. There are lots of green leaves which my son thinks are darker than they were in the spring but it is hard to tell.

Here is a close up of the leaves.This time he measured around the trunk and found it to be 28 inches in circumference.

This is what he noticed had changed the most about the tree. It had these sprouts coming up from the bottom of the trunk. We usually snap these off as they sprout but my son wants to leave them just to see how they grow.

We are anxious to compare our summer tree with our autumn tree!
