It looks like a Burl. They are natural non-harmful (think of them like scar tissue maybe, resulting from injury or infection) deformities in the grain of trees. Both hardwood & softwood trees can develop burls. (FWIW, I'd guess based on the bark & needles laying in the folds of the bark in the first picture that this tree is some sort of conifer.)

There are two important factors when bowmaking: Flexibiliy, i.e. how easy the wood is to bend Strength, i.e. how much force you can put into the wood before it breaks. If you are just interested in a toy bow that doesn't shoot to hard or far then flexibility is your main concern. You want thinnish green wood which tends to be the most flexible. If you ...

For the purpose of my answer I'm going to assume there aren't any special considerations like a tall tree on a small lot. In general I think this is the best procedure: Cut down one tree. Trim off all the branches. Build a big pile of small branches that aren't useful for firewood. a. Load this stuff into a trailer and dispose of it as appropriate when ...

Was it safe? Yes, you were not in any danger here (unless your tree was a Charlie Brown Christmas tree). Was it the best thing to do? No, for a couple of reasons, the most important being that it does not comply with leave not trace ethics, and can badly scar the tree. It's also no good for your rope, dragging your rope through dirt and sap can ...

Sugar maples, like other maples, flower in early spring. The flowers aren't very impressive. The leaves of sugar maple are usually fully expanded three to four weeks after the leaf buds begin to swell in the spring. The flowers emerge soon after the leaves and are in full bloom within a week. ...Fruits that result from flower pollination usually mature ...

Sap flow in trees is a result of sap pressure accumulated in the roots during a frost, which is then released when the temperature thaws during the day. Many tree species cannot be harvested because they do not develop high enough sap pressure to bleed (according to Venerable Trees, Inc.). One farm in BC reports that birch sap is harvested just after maple: ...

You may like the look, but those trees are in the process of being killed by a nasty invasive, Oriental Bittersweet (Celastrus orbiculatus). It is one of the more common invasives in MA. There have been many things writting about this invasive. It's been on any list of invasive plants in MA that I've seen. Do a search and you'll see. DCR (MA Department ...

In the US southwest, Juniper was commonly used by native peoples. I've heard it said that one can still find living Juniper trees around the southwest that have apparent 'slices' taken out of them where material was removed to shape a bow. Also, a quick google search turned up this site with a seemingly comprehensive list of woods that will work for bow ...

When I was a kid I repeatedly made simple bows from hazel trees/shrubs. The main advantage here is that it grows in very handy, more or less uniformly thick branches that are very appropriate in size to use as bows (also make good walking sticks/spears). As strength/durability of the bow was never an issue we used freshly cut, green branches - obviously a ...

You are probably finished with this project by now, but I'll weigh in with our experience for others searching for this answer down the road. We were wondering the same thing about how to attach horticultural signs to trees a couple of years ago. We manufacture interactive plant tags for trees and other plants and many of our users attach our larger signs ...

I was pleased to see the photos of the burls; it's been some time since I had thought of all of the splendid uses Native Americans and others had found for burls, so I hope no-one minds my digression. Burls are caused by wounds to trees, as has been mentioned. But far from making the tree unattractive, burls had been valued! They had been sought out by ...

You do not say what size tree, but to me big means something like 1/2 meter or more diameter trunk. Presuming a living tree with no obvious movement of the roots the tree was infinitely stronger than your quick draw or chains or bolts holding them to the rocks. "Was it safe" is not the right question "was it safer than what I already accepted as safe enough" ...

Short answer: If the tree is a living and thick one, then it was OK. That being said, there are several reasons you should had done a proper anchor with multiple points (trees, in this case) and equalized, and then walked back again to the top. One simple drawback of your approach is, that the friction between the rope and the tree trunk, when you recall ...

I have been doing quite a bit a research on rope as I am nearing the completion of my magnificent 40 foot tree swing project. in all that I have gathered from seemingly knowledgeable sources...braided polyester is what you want, for durability, and non-stretch. After that it seems the fallback would be a natural rope fibre requiring replacement at least ...

I'd go with either polyester rope or Dyneema cord. Both are resistant to UV and neither rot nor stretch. Dyneema has superior wear resistance and is much stronger by weight, but is probably more expensive. Maybe have a look at an (online) marine store. Other yarns such as polyamide (nylon), polypropylene, etc. tend to have inferior UV resistance. I'd try ...

Expand Farm Products sells the insulator to attach signs to trees using a rubber rope to allow the tree to keep growing. They just started marketing the sign hold tape along with their insulator to post any of your signs to trees quickly and easily. www.expandfarmproducts.com or on facebook at Expand Farm Products Llc.

Agreed. The Audubon guides are the best that I know of because you can search in the flower section, the bark section, or the leaf section for your target tree. Not familiar with the apps, but I'm sure they do the same thing if not more. My personal favorite for tree walks with kids? The Sibley Guide to Trees. Here's why: Really good color drawings ...
