I know that there are two kinds of timber harvests: ugly and really ugly.
The first action I would suggest is to break out of this mindset. Trees are plants, just like our blackberry bushes and rhubarbs. We harvest all kinds of plants for our usage, and timber shouldn't be seen to be any different. There are lots of good reasons to harvest timber — clearing out diseased trees, trees highly susceptible to coming diseases/pests, reducing a monoculture, thinning to encourage healthy growth, etc.
I would ask questions about a few different angles:
1. Water flow & erosion control. Are there streams on the property? What will be the protections to these streams during harvest? Will they be building new roads/skid paths? What kind of protections will be made to these when they're done? (ex: water bars)
2. Impact to land. What kind of equipment are they planning on using? Larger equipment usually results in a much lighter impact on the land (bigger tires/tracks spread out weight more evenly and large equipment like CTL loggers can take a tree down without it ever hitting the ground). How will they be moving the logs to the landing? Vehicles are generally less impactful than pulleys here.
3. How will they be selecting the timber? High-grading is the worst possible option. Ideally you want your forest to be mostly widely spaced trees interspersed with open areas and dense areas. The goal is to give existing trees maximum sunlight, new nursery areas full sunlight, and dense thickets for wildlife to dash between. Clear cutting entire properties is obviously extremely damaging, but in small sections can often result in a much healthier ecosystem than even selective thinning.
4. What will they do with the slash? This is really up to you — you can leave some brush piles for wildlife habit if they don't pose a fire threat, burning slash often kickstarts the natural succession process by sweetening the soil and stratifying tree seeds. Or you could have them chip it.
5. Will they be planting new seedlings? Doing a controlled burn? Both of these options are great for replenishing the forest in the harvested areas.
All in all, I'd just recommend trying to talk to the forester more. Explain your goals to them and see what they think. If you don't like how they think, look for another forester to get a second opinion. Once you have someone on your same wavelength, they can help with the technical details of the harvest to better your goals.
