Change in Plant Hardiness Zones, 2012 to 2023 in New York State

Change in Plant Hardiness Zones, 2012 to 2023 in New York State

I did some raster math to compare the 2012 plant hardiness zones to the 2023 plant hardiness zones. Most of the state was bumped up one zone, though many of the higher elevation areas remained in the same zones.
 
Interestingly enough, the Western Catskills actually fell back one or two colder Plant Hardiness Zones with the latest maps while the most of the state advanced to a warmer plant hardiness zones. The Western Catskills had a handful of particularly cold mornings in recent years, though maybe it's also an artifact of how PRISM krigings the temperature data.

I am also not convinced the area around Chautauqua Lake jumping from 5B to 6B or the Southern part of the Tug going from 5A to 6A. It's possible, but I am thinking it's a kriging artifact.
 
The 2012 Plant Hardiness Zones were really old data, 1975-2006, even at the time they were released. The 2023 Plant Hardiness Zones are 1990-2020, which is much more up to date. This is very problematic as the late 1970s were an exceptionally cold winters in New York's history. Old Forge hit negative 52, on February 18, 1979 which throws everything off.
 
Minor edits to this map on 11/7. Basically rather then comparing them using raster math, I did the contours separately for each year and then joined them against and did the math on the vector. Rethinking it, the later method is more accurate then with raster method, at least in comparison of other maps. That said, either way the result is very similar, we are talking about splitting fractions of a degree, which make the categories slightly different. Like anything, it's a matter of how you ask the question and the methods used.

Moorefield, West Virginia

Moorefield, West Virginia

Corridor "H" is the highway prominently shown in the center. It is an elevated highway through the valley. Pilgrim's Pride slaughterhouse is seen in the lower left corner, they process birds grown at farms along the Sweedlin Valley and some of the other agricultural areas in valleys. The river in the center is the Potomac River.

1000 Feet To Highway

Living near a superhighway can be convenient, but it's also can be unhealthy. Noise pollution and air emissions can lead to a shorter lifespan. The greatest impacts of highway pollution are felt by people who live, work, or recreate within 1,000 feet of a limited-access road.

Proposed Exit 25 Interchange with Interstate 88

Proposed Exit 25 Interchange with Interstate 88

For many years in the 1960s, the Thruway Authority was opposed to creating an exit from the Thruway specifically for Interstate 88 due to the high cost of staffing toll booths. Ultimately they agreed but originally they had planned a connector at Exit 25. This was discarded in part due to concerns with run off from road salt into the Watervliet Reservoir. 

Eastern Albany Pine Bush Summits Over 325 Feet

This map shows the 300 or so points in the Albany Pine Bush Study Area, that are above 325 feet in elevation and are a prominence around the surrounding land. The landfill is the highest peak at 432 feet above sea level, while Overlook Dune near the Albany Pine Bush Discovery Center tops out at 374 feet above sea level. The highest dune can be seen from the Traux Trailhead on Kings Road, which tops out 390 feet above sea level.

Data Source: Albany County LIDAR Digital Elevation Models. Dune peaks obtained by using the GRASS plugin in QGIS with r.param.scale, method=feature, then r.reclass to remove anything but value=6 to create peaks, then r.tovect to convert to vector areas, then used zonal statistics to find the maximum value on the peak, then extracted the centroids of the polygons.

NY Natural Heritage Community Occurrences

Unique habitats and ecosystems in New York. Zoom in and use the satelight view for best results. Click for details on the habitat. Features represent occurrences of rare or high-quality natural communities (ecological communities), as recorded by the New York Natural Heritage Program. An occurrence is one natural community type at one location. Examples of community types include deep emergent marsh, red maple-hardwood swamp, dwarf shrub bog, hemlock-northern hardwood forest, and tidal creek.

Hannacroix Ravine Preserve

Hannacroix Ravine Preserve spans 415 acres and is managed by The Nature Conservancy, welcoming visitors to explore its natural beauty. Situated on the western outskirts of New Scotland, it serves as the origin of Hannacrois Creek. The highlight of the preserve is Sliding Rock Falls, a 30-foot waterfall visible from the main trail that loops around the area, totaling about 3 miles. While the hike is moderate and generally uneventful, hikers may catch a glimpse of the falls from certain vantage points along the trail.
