The Forest Vegetation Simulator (FVS) is a family of models used for predicting forest stand dynamics (tree growth, mortality, regeneration, management, disturbance, etc.) throughout the United States. The Forest Health Assessment and Applied Sciences Team supports a variety of insect and pathogen models that allow FVS users to incorporate forest pest disturbances into their FVS projections.
The family of FVS models comprises 20 different geographic variants, each calibrated to local conditions. Insect and disease models for FVS are developed and maintained in partnership with Forest Health Protection and the Forest Management Service Center. The models take one of two forms: (1) FVS model extensions, which are integrated into and interact directly with the base FVS model, or (2) keyword component (kcp) files, which contain FVS keywords instructing the base FVS model to perform specific calculations and activities (such as mortality) during a simulation. Availability of insect and disease models varies by FVS variant, as summarized below.

Located more than 2,000 feet above sea level, this garden is filled with surrealist structures, created by eccentric English poet Edward James, in a subtropical rainforest. Natural waterfalls are interlaced with pools and the towering structures.
Located in Villandry in central France, this Chateau is known for its spectacularly manicured gardens. The chateau was purchased in 1906 by Joachim Carvallo who spent a large amount of time curating the extravagant gardens.
One of the most famous gardens in the world – and certainly the best spot to catch a glimpse of the Dutch tulips – more than seven million tulips line the winding river of Keukenhof Gardens.
These 600-acre gardens were originally purchased with the intention to make a fruit plantation but were instead turned into a wildlife conservation project. They are now divided into nine different sections including the ‘Flower Valley’, ‘French Garden’ and ‘Stonehenge Garden’.
These gardens were established between 1931 and 1940 when a new owner completely transformed the gardens of Villa Taranto to make them the floral oasis they are today.
These gardens cover an impressive 1,077 acres, woodlands and meadows. The gardens came to fruition after Pierre S. du Pont purchased them in 1906 and have been wow-ing visitors ever since.
This garden was laid out by Ludwig Remy in 1821 and is situated on the grounds of Hofburg Palace. It's famous for its rose garden with over 3,000 rose bushes and 200 different cultivars of roses.
Kew Gardens has long been a Saturday afternoon staple for Londoners but with the Temperate House – the largest Victorian glasshouse in the world – reopening next month, there’s been no better time to visit.
If you visit one garden in your life, let it be this one. Claude Monet’s garden, at the home he lived in in Giverny, France, is, quite literally, like something out of a painting. A quick train ride from Paris, the garden is split into two parts - a flower garden called Clos Normand and a Japanese-inspired water garden.
