How to pick the right technology to hit your biodiversity goals

With new regulations and requirements coming out of the UK, EU, and US, it’s clear that biodiversity and land sustainability is being taken as seriously as climate change.

As these new laws and expectations get put into place, you’ll have targets and commitments to hit. How are you planning to track, measure and report on your land assets biodiversity, much less start improving it?

Traditional methods to measure biodiversity

You really have two options for this: do it manually or use technology.

We’ll get to the technology options in a moment, but first let’s talk about how to do this manually.

You would need to create a plot map(s) using publicly available data, typically from government sources. Then you’ll need to hire a team of ecologists to go out and manually assess each habitat.

Usually, it would be 1-2 ecologists on site to do a survey, they would then create a report, that would be sent to another team of ecologists to be verified, and then they’d report the findings to you.

For every 20-100 hectare site it would take somewhere between 4-8 weeks for this process. Usually about a week surveying the site (more the larger the site), and the rest of the time reporting and reviewing.

For one site this is a perfectly acceptable approach – the problem really lies with the ability to scale.

If you had multiple sites that needed assessments, you’d need to hire multiple teams all working in parallel or rely on the same team to go one by one, which could take years. Either way this gets extremely expensive and at a certain point, just isn’t realistic if you have hundreds or thousands of sites across a country.

The costs, both in time and money, present a burden to companies in order to just stay compliant. There must be an easier way so that it makes business sense to be a good corporate citizen, on top of making ethical sense.

This is where remote sensing technology has gotten to place where it’s viable to measure sustainability in a holistic way, taking the pressure off companies.

Technology options to help you hit your biodiversity goals

There are three main remote sensing techniques, each with their own pros and cons.

Drones

First up we have drones. Simple enough concept, attach a camera to a drone and have an operator fly a property. Once the images are back you can have an ecologist analyze the images, or a data science team to piece it together if you’re using LiDAR.

Certainly quicker, at least for scanning, than manual surveys, but this method can get quite costly when doing multiple sites. And at the end of the day, you have to make a choice between sending a drone operator out or an ecologist, if you can still only do one site at a time, you might as well send the ecologist.

Aerial

Another popular method is aerial imaging, both from planes and helicopters.

This offers pretty good quality of imaging, and gives more scale than drones do, however if you’re dealing with sites spread throughout a state or country, you’re still looking at multiple flights.

Especially if you want to rescan every year to measure your progress, this can get costly, not to mention the emissions from these constant flights.

Satellites

Finally, there’s satellites.

Satellites offer sustainability at scale. Whether it’s one site or 10,000, you can scan and analyze them all at the same time. The ecological survey and analysis process can happen in days instead of months, plus rescanning your sites on an annual basis is cost effective, so you’ll be able to actually track and measure your progress.

The main drawback from satellites is resolution. Satellites have around 30cm resolution, while aerial has 10cm. Both give plenty of pixels to meet the minimum mapping unit required by regulators, but it’s still a bit of a tradeoff between cost effectiveness and scale or resolution.

The good news is that satellites are expected to get 10cm resolution as soon as 2023 so it’s truly a future proof technology.

These work together

No matter what some might say, these don’t have to be competing technologies either. They each have their place.

For instance, we’ve seen many clients use ecologists or aerial imaging to do their initial assessments. They want as accurate initial imaging as possible. Then they work with us to provide continuous monitoring to track, measure, and report on their biodiversity progress all within one platform.

If the satellite scans flag an area of concern, they may send an ecologist out to do a targeted assessment, which is a much more efficient process for biodiversity management.

Going beyond the data

Regardless of which remote sensing method you feel is right for you, you need to consider what comes next.

Getting the measurements or assessments is a great first step, but regulators want action plans and progress.

This is where an AI solution really shines. By combining our AI with satellite imagery or other data sets, we can help you baseline, plan, track and report on progress to ensure that you hit your biodiversity targets.
