Christmas Green

Christmas green (Lycopodium obscurum) is a terrestrial clubmoss in the family Lycopodiaceae, native to eastern North America and parts of eastern Asia. It is one of the most recognizable clubmosses in North American forests, forming upright, tree-like shoots that superficially resemble miniature conifer saplings. The species grows in moist, cool deciduous and mixed forests, often on acidic, humus-rich soils. Lycopodium obscurum reproduces via spores produced in terminal strobili — cone-like structures at the tips of upright branches. Clubmosses are ancient vascular plants with a lineage extending back over four hundred million years, representing one of the earliest groups of land plants to evolve vascular tissue. They are not true mosses but belong to the lycophytes, a separate lineage from ferns and seed plants. Christmas green has historically been harvested extensively for holiday decorations and wreaths due to its evergreen, decorative appearance and the fact that cut branches remain fresh for extended periods. Over-harvesting in the twentieth century significantly reduced populations in accessible areas of the eastern United States. Clubmosses reproduce and grow slowly, making them vulnerable to over-collection. Ethical wildcrafting guidelines recommend sparing collection to allow populations to recover.

The largest wild cat on Earth, tigers can exceed 300 kg and inhabit forests from the Russian Far East to Southeast Asia. Solitary ambush predators with distinctive orange and black striped coats that provide camouflage in dappled light. Critically endangered, with fewer than 4,000 remaining in the wild due to poaching and deforestation.
