FIRST ON FOX: Rep. James Gallagher, R-Calif., urged FBI Director Kash Patel on Monday to crack down on illegal marijuana cultivation operations in Northern California.

Gallagher sent the letter after the Siskiyou County Sheriff’s Office reported extensive illegal cultivation and illegal immigrant labor in the region. The congressman said the operations have harmed local ranchers, depleted groundwater supplies and raised concerns about potential financing from Chinese organized-crime networks.

"Entire rural properties are now covered with rows of makeshift, plastic-covered greenhouses, known as ‘hoop houses,’ where marijuana is cultivated using groundwater hauled in from nearby wells," Gallagher wrote in a letter exclusively obtained by Fox News Digital.

"The consequences have been devastating, with residents facing depleted water supplies and threats to their safety, while local farmers and ranchers contend with increased competition for groundwater and the risk of contamination to their agricultural land," he continued.

The letter cited estimates of as many as 7,000 illegal growers in the Mount Shasta Vista subdivision alone. Gallagher said illegal cultivation has also expanded onto federal lands, including the Shasta-Trinity National Forest.

Gallagher also raised concerns that Chinese organized-crime networks could be financing or directing some of the operations.

"In Siskiyou County, investigators have traced cultivation properties to individuals residing outside the county, while those managing the grows often have no apparent ownership interest," Gallagher wrote. "These arrangements raise serious concerns about who is actually financing and controlling these operations and whether the ownership arrangements are intended to conceal their involvement."

Gallagher pointed to a 2018 federal investigation in California involving an illegal marijuana growing operation that authorities said was funded with money from China. The investigation led to federal forfeiture actions involving more than 100 properties in the Sacramento area, according to the U.S. Attorney’s Office for the Eastern District of California.

The congressman also cited environmental damage linked to the illegal grow sites, including the use of toxic pesticides.

"Compounding these concerns is the widespread use of highly toxic pesticides, including chemicals banned in the United States and products bearing Chinese-language labels that are suspected of being illegally imported," Gallagher wrote.

Siskiyou County investigators have identified at least 27 pesticide compounds at illegal grow sites, according to county findings. Officials have warned that the chemicals could pose risks to residents, law enforcement officers and first responders.

A professional python hunter who doubles as a professional alligator wrestler, according to his Instagram bio, helped catch "the longest live captured reticulated python ever caught in Puerto Rico."

Working with Proyectos Retic, a group of python hunters in Puerto Rico who collect data and specimens about the reticulated python, Snakeaholic aka Kevin Pavlidis helped snag a reticulated python that measured 18' 4" long.

This gigantic snake was held up by eight people standing shoulder-to-shoulder to show just how big of a snake they're dealing with. They tracked it down after it was "spotted strangling a pet cat behind a house."

There was no mention of whether the pet cat survived the ordeal or not. These hunters had a snake to catch. But as you can clearly see, that thing can easily take down more than a pet cat.

The reticulated python is an invasive species in Puerto Rico, much like the Burmese pythons are, in Snakeaholic's home state of Florida.

"It took all my tracking skills and 20 minutes of searching to find this snake down in the jungle," Snakeaholic wrote about tracking down the snake after it was chased down a mountain away from the cat it was strangling.

"Removing this invasive apex predator is one more step towards restoring the delicate balance of the ecosystem out here in Puerto Rico and I am proud to be a part of this incredible conservation work!"
