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.

In late summer when many other flowering shrubs have lost steam, this plant is in its full glory with pink, white, lavender, or even blue flowers that bloom well into fall. New types grow in a column (pillar) shape that's sized right for small gardens.
This spring-blooming shrub has a mounded form with gracefully arching branches. Some types are low growing and work well as a beautiful ground cover too.
This native plant has elegant arching branches dotted with clusters of creamy white or pink flowers in late spring. It's fast growing and can become quite large, so give it plenty of room or look for dwarf varieties if you're tight on space. Some types have beautiful wine-colored or golden-orange foliage.
Some like it hot! These lovely shrubs ignore the heat and bloom all summer long with frilly, vibrant flowers in shades of white, purple, crimson, or pink. Some types become small trees; others are dwarf varieties that remain three to four feet tall and wide.
As the rest of your garden winds down, this little beauty is taking off. This sun lover, also called bluebeard, has charming blue blooms from late summer to fall. Plus, bees and butterflies love it! Plant it in masses along borders for maximum impact.
This reliable bloomer rarely needs your attention. New types maintain their mounded shape without pruning. Long-lasting clusters of red, white, or pink flowers offer beautiful contrast against lime green, deep green, or gold foliage. It's equally at home in mass plantings, as a low hedge, or alongside perennials.
This stunning shrub is one of the few plants that can be grown in almost every climate. You'll get three seasons of display: bright flowers in summer, faded tones in fall, and papery dried blooms that linger on the plant over the winter. These shrubs are categorized into types (panicle, smooth, oakleaf, bigleaf, and mountain) that have different needs, so read the plant tag before buying.

If you live in California, much of the southwestern part of the United States, Florida, or Alabama, Lara Hermanson, principal and co-owner of Farmscape, says that citrus trees may be a great option for you. "I love growing orange, clementine, lemon, and kumquat trees in our farmscapes," she says of some of the sweet and tart varieties that fit under that banner.
Mango trees are lush, tropical staples that produce juicy, sweet fruits, says Vernic Popat, the CFO of PlantOGram.com. "Mango trees thrive in full sun and require well-drained soil to prevent root issues," she says.
This self-pollinating fruit is such a beloved one that one state actually uses the fruit as part of its nickname (it’s Georgia)! "Peaches offer a juicy, sweet, and slightly tart flavor with a fragrant aroma, perfect for fresh eating, desserts, and canning," Popat says.
These evergreen trees are known for the sweet and tangy pink fruit that typically has a pink center and a green outer layer. Guava trees thrive in warmer regions; they don't tolerate frost at all, Hermanson says.
Growing Asian pear trees will give you access to these delicious fruits, which can be enjoyed in a variety of ways. "Asian pears are known for their crisp texture and a sweet, melon-like flavor when ripe, making them refreshing to eat raw or in salads,” Popat says. Plant your Asian pear tree near another variety of pear—they require cross-pollination with another pear variety for best fruit production.
Another regionally evergreen tree, Popat says that lychee offers growers beautiful foliage and sweet, aromatic fruits. "They perform best with full sun to partial shade and need protection from wind," she says.
The avocado, alligator pear or avocado pear (Persea americana) is an evergreen tree in the laurel family (Lauraceae). It is native to the Americas and was first domesticated in Mesoamerica more than 5,000 years ago. It was prized for its large and unusually oily fruit.[3] The tree likely originated in the highlands bridging south-central Mexico and Guatemala.[4][5][6] Avocado trees have a native growth range from Mexico to Costa Rica.[7] Its fruit, sometimes also referred to as an alligator pear or avocado pear, is botanically a large berry containing a single large seed.[8] Sequencing of its genome showed that the evolution of avocados was shaped by polyploidy events and that commercial varieties have a hybrid origin.[9] Avocado trees are partly self-pollinating, and are often propagated through grafting to maintain consistent fruit output.[10] Avocados are presently cultivated in the tropical and Mediterranean climates of many countries.[4] Mexico is the world's leading producer of avocados as of 2020, supplying nearly 30% of the global harvest in that year.[11]

The hedgehog is a round and spiny forager native to Africa. They can be wonderful pets, but they are nocturnal and often sleep a lot during the day. They tend to get frightened very easily and will roll up into a prickly ball when startled. Despite their sharp quills, these low-maintenance cuties have gained a lot of popularity as pets. Hedgehogs are cute, delightful, and quiet animals. Due to their spines, hedgehogs aren’t very cuddly animals. However, they are very friendly and lively pets. They are very social, especially if they’re handled regularly from a young age. It is undoubtedly one of the cutest animals on earth.
