For property owners in Nevada County and Placer County, clearing dense brush by hand is slow, expensive, and often dangerous. When you have acres of overgrown manzanita, blackberries, or Scotch Broom, you need heavy industrial solutions.
Irish Tree Surgeon provides professional forestry mastication services to turn overgrown jungles into park-like settings instantly. Using high-horsepower masticators (forestry mulchers), we grind vegetation down to the soil level, leaving behind a nutrient-rich mulch layer that prevents erosion and suppressing regrowth.
What are Forestry Mastication Services?
Mastication is the most efficient method for fuel reduction on large properties. Unlike a bulldozer that scrapes the soil (damaging the land) or a hand crew that creates massive burn piles, our masticators surgically grind brush and small trees where they stand.
The Benefits of Mastication:
- Speed: One machine can do the work of a 10-man hand crew in a single day.
- No Burn Piles: We eliminate the need for dangerous burn permits or waiting for “burn days.” The fuel is processed instantly.
- Soil Health: The mulched material retains moisture in the soil and prevents the erosion often seen after bulldozing.
LTO Land Clearing for Development
Are you preparing a lot for new construction in Grass Valley or Auburn? Before you can break ground, you need a clean site. As a licensed timber operator (LTO), we specialize in lot clearing for development.
We handle the complete site prep package:
- Tree Removal: Cutting and removing trees within the building envelope.
- Stump Grinding: Eliminating stumps to allow for foundation work.
- Access Roads: Clearing 15ft vertical clearance for fire truck access roads (a requirement for building permits).
Large Acreage Fuel Reduction
For owners of large estates in Penn Valley or ranch lands in Browns Valley, fire safety is a massive undertaking. Our large acreage fuel reduction programs are designed to create defensible space on a grand scale.
We create “Shaded Fuel Breaks” by removing the underbrush while leaving the healthy canopy trees intact. This stops a ground fire from climbing into the trees, potentially saving your forest during a wildfire.
Equipment Rental vs. Hiring an Operator
Many homeowners consider a brush masticator rental to do the job themselves. However, forestry mulchers are dangerous, heavy machinery that require skilled operation to avoid damaging “keeper” trees or hitting rocks that can shatter expensive teeth.
Don’t risk injury or a $5,000 repair bill on a rental unit. Our operators are highly trained to navigate steep terrain and maximize the efficiency of the machine, saving you time and money in the long run.
