Native Oak Tree Ranges in the U.S.

Oaks are principally temperate zone trees or shrubs, estimating about 600 species globally. Oaks have remained on the non-glaciated territories of North America following the Cretaceous Period.

According to the U.S. Forest Service, 50 oak species are represented in 2/3 of the eastern North American wood cover types and dominate 68% of hardwood forests (77 million hectares or 191 million acres).

The invasion of urbanization, agriculture, and hydrologic projects continue to affect oak forest types negatively. Such influences may require the establishment of preservation areas for vulnerable species.

In the southern U.S., forest management methods prefer conifers displacing hardwood forests in rich bottomlands. A new cause of concern includes the threat of displacement of native oaks by different exotic species. Moreover, forest types are placed at risk by introducing not only non-native plants but insects and diseases. 

In 1997, a fungal pathogen (Phytophthora ramorum) was known as the cause of the Sudden Oak Death in California. Searching for potential hosts has found some sensitive species of eastern red oaks. Additional susceptible hosts include commercial nursery stock, which enhances the chance of the Sudden Oak Death expanding to eastern North America.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

The Appalachian Mountains, the Scottish Highlands, and the Atlas Mounts in Africa were the same mountain range

The Central Pangean Mountains was a prominent mountain ridge in the central part of the supercontinent Pangaea that extends across the continent from northeast to southwest through the Carboniferous , Permian Triassic periods. The mountains were formed due to a collision within the supercontinents Gondwana and Laurussia during the creation of Pangaea. It was comparable to the present Himalayas at its highest peak during the start of the Permian period. It isn’t easy to assume now that once upon a time that the Scottish Highlands, The Appalachian Mountains, the Ouachita Mountain Range, and the Atlas Mountains in northwestern Africa are the same mountains , once connected as the Central Pangean Mountains.

Human Emotions Visualized

Despite significant diversity in the culture around the globe, humanity's DNA is 99.9 percent alike. There are some characteristics more primary and typical to the human experience than our emotions. Of course, the large spectrum of emotions we can feel can be challenging to verbalize. That's where this splendid visualization by the Junto Institute comes in. This visualization is the newest in an ongoing attempt to categorize the full range of emotions logically. Our knowledge has come a long route since William James suggested 4 primary emotions: fear, grief, love, and rage. These kernel emotions yet form much of the basis for current frameworks. The Junto Institute's visualization above classifies 6 basic emotions: fear, anger, sadness, surprise, joy, love More nuanced descriptions begin from these 6 primary emotions, such as jealousy as a subset of anger and awe-struck as a subset of surprise. As a result, there are 102 second-and third-order emotions placed on this emo
