Right before Allagash falls there were very few evergreens, the river being lined by large deciduous trees all around.
I have opted to document he life of this Ash Tree through 2014. It is alongside one of the necklace of lakes that circle the Great Glasshouse at the National Botanic Garden Wales.
Tree in center-right is an Alaska yellow cedar (Cupressus nootkatensis). The forest type is a mountain hemlock-silver fir (Tsuga mertensiana-Abies amabilis) forest. Mount Rainier National Park.
at HaRamo wine brewery. this shot was taken under the grape trees. Japanese grape firm let train over the head like a roof.
When outter dark green layer of leaf is scratched off, it will heal with tan scar. Tree leaves have history of use as playing cards. Flower contains sticky sap that can be used as weatherproof caulking. Native to Hawaii and is invasive, seed spread by birds.
I switched from Aperture to Lightroom as of January 1, 2013. This is the first photo I processed using the new software. I think I will like using LR very much.

Edit: This was the original Magic Tree. It has now been retired, and a new one at Cherry Hill has taken its place.

This tree is near the main pond close to the cafe and is also a big tree. There are several others of almost equivalent size in SBG's.
IDENTIFYING AUSTRALIAN RAINFOREST PLANTS,TREES & FUNGI - Flick Group --> DATABASE INDEX
Gray tree frogs are, as their common name implies, predominately gray in color. They can be light or dark gray, or light gray with darker gray, black, yellow or green mottling. They are relatively small compared to other North American frog species, typically attaining no more than 1.5 to 2 inches (4cm to 5cm) in length. Their skin has a lumpy texture to it, giving them a warty appearance. They are virtually indistinguishable from the Cope's Gray Tree Frog, Hyla chrysoscelis, the only readily noticeable difference being their call.
Both Hyla chrysoscelis and Hyla versicolor have bright orange patches on the hind legs, which distinguishes them from other tree frogs, such as Hyla avivoca (Martof et al. 1980). Both species of Gray tree frogs are slightly sexually dimorphic. Males have black or gray throats, while the throat of the female is lighter (Tyning 1990).
Tadpoles have a rounded body (as opposed to the more elongated bodies of stream species) with a high, wide tail that can be colored red if predators are in the system. Metamorphosis can occur in as little as 2 months with optimal conditions. At metamorphosis, the new froglets will almost always turn green for a day or two before changing to the more common gray.
Geographic range
Gray tree frogs inhabit a wide range, and can be found in most of the eastern half of the United States, as far west as central Texas. They also range into Canada in the provinces of Ontario and Manitoba, with an isolated population in New Brunswick.
Behavior
Gray tree frogs are primarily arboreal, spending time in wooded areas, usually not far from a permanent water source. On rainy evenings they can often be found calling in or near shallow, temporary pools of water. They are nocturnal and insectivorous, consuming most any small arthropod they can catch. Mating occurs throughout the spring and summer months.They also will change colors, as in a light green to a gray, to match their habitat.
Gray Tree Frog, Hyla versicolor
In captivity
Wild caught gray treefrogs are frequently found in the pet trade. They make excellent, undemanding captives. A moderately humid vivarium of live plants is generally quite adequate to house them, along with a varied diet of commercially available crickets, small moths and other insects. Be sure to provide a source of water for your tree frog or mist frequently to keep the skin moist. These pets are common in and around the Oklahoma region, and are nocternal like many other tree frogs.
Conservation
There are several environmental changes that affect Hyla versicolor, including ones that result from human land use and development. Studies indicate that Hyla versicolor is moderately tolerant of pH levels as low as 3.5. UV-B radiation does not affect egg and larvae survival, but does reduce swimming activity. 200 – Concetrations of 2,000 micrograms per liter of Atrazine, a globally used herbicide used against pre- and post-emergence broadleaf and grassy weeds in major crops, gave tadpoles 10% less body mass and were 5% shorter than normal water concentrations. The larval period also took 5% longer in the greater concentration. Carbaryl, also known as Sevis, is the third-most-used insecticide. By itself, it does not hurt things, but UV-B radiation photoenhances its toxicity, reducing swimming activity and killing 10% - 60% of the tadpoles exposed to weak concentrations of this chemical for long periods of time. If predatory cues were also present, it killed an even greater 60% - 98% of the tadpoles.
