Presenting at ACF 2017 in Tahoe

Greetings from the beautiful shores of Lake Tahoe!  We're exhibiting at the Association of Consulting Foresters meeting in Incline Village, Nevada.  We're giving lots of demos of the new Plot Hound customization features and our new and powerful (and free!) plot layout tool in Canopy.  We're also excited to be bringing the power of remote-sensing to all consulting foresters with our CruiseBoost service.  We've spent the last year automating much of our satellite image analysis so that foresters working on properties as small as 40 acres can still take advantage of the power of remote sensing.

It's always great to meet consulting foresters using Plot Hound and CruiseBoost to make their inventory work easier - swing by the booth if you're in town!

Plot Hound is turning 6, and we're celebrating with a brand new version!

Screen Shot 2017-04-28 at 6.18.54 PM.png

For the last six years, SilviaTerra has been striving to build the best possible mobile cruising experience. Our 100% free Plot Hound application has been put to use in plots across the country (and the world!), with continuous improvement that has only been possible thanks to the feedback and suggestions from the thousands of cruisers who have used Plot Hound.

That’s why we’re excited to announce that we’ll soon be making Plot Hound ever better with a major new release. Version 6.0 will be out this summer, and it’s packed with new features. The biggest change is custom data types and validation. This means you’ll have the ability to go beyond a few generic data entry fields, increasing flexibility and reliability of your data. We know every cruise is different, and now that Plot Hound is being used all over the world it’s more important than ever that we can tailor the cruising experience to you.

Want to use the new Plot Hound on an upcoming cruise? Feel free to reach out to us at We’re now officially opening the version 6 beta signup - for both Android and iPhone.

Launching the "Biometrics Bits" column in the Forestry Source

forestry-source.jpgWe're excited to announce that the SilviaTerra biometrics team just published its first "Biometrics Bits" column in the Forestry Source - the Society of American Foresters newspaper. Our first article explored the question - "What is the 'Right' Amount of Inventory Information to Collect?"

Using the fantastic FIA dataset, SilviaTerra's Lead Biometrician Dr. Nan Pond simulated many different cruising methods and intensities. Using this approach, we arrived at a rigorous and quantitative answer to the question "when does spending an additional dollar on inventory result in less than a dollar's worth of better management decisions?" in a variety of forest types in the US.

We're excited to share our thoughts on biometrics with the wider forestry community - stay tuned for plenty more articles!

Brian Clough joins SilviaTerra

The SilviaTerra team is thrilled to announce our newest member, Dr. Brian Clough.  Brian comes to us after completing several years of postdoctoral research at the University of Minnesota.  He brings a great set of skills to complement our current biometrics team, including experience with biomass and carbon modelling, and a solid background in Bayesian modelling techniques.  

Brian is originally from the northeastern US, where he earned his PhD in Ecology and Evolution at Rutgers University.  SilviaTerra’s remote work system will allow him to continue to call Minnesota home for the time being. He’s already hard at work improving our automated height modelling systems, along with learning about the rest of our systems.  Welcome, Brian!

SilviaTerra founder speaks at Center for Business and the Environment at Yale 10 year anniversary @ Google SF

SilviaTerra founder Zack Parisa spoke yesterday at the Center for the Business and the Environment at Yale 10 year anniversary event hosted at the Google San Francisco office.  Other speakers included Dr. Indy Burke, the Dean of the Yale School of Forestry & Environmental Studies and Stuart DeCew, the Director of CBEY.

Zack spoke about how SilviaTerra originated from his Yale M.F.S. thesis work on helping rural Armenian villages manage their forests better.  Without accurate and recent forest inventory information, any management planning was useless.  In response, Zack developed what became the core SilviaTerra satellite imagery analysis technology so that he and his small team of local foresters could develop a forest inventory data layer across much of the country.

The focus on enabling better management decisions has been at the heart of SilviaTerra since the very beginning.  From our original work enabling villagers in Armenia to manage their firewood supply to helping many of the largest American environmental and industrial landowners achieve their conservation and production goals, SilviaTerra has always been driven by the idea that better data can enable better decisions.  Zack described how richer information about our forests is enabling the valuation and management of new, non-fiber ecosystem services and the role that information-providers like SilviaTerra play in building a future where our forests are managed efficiently, accurately, and equitably.

If that sounds like a future you'd like to help build - we're hiring!

Mike Holkesvik joins SilviaTerra

We're excited to announce the newest member of the SilviaTerra team - Mike Holkesvik!

Hailing from South Dakota, Mike grew up where the deer and the antelope play. He spent his childhood in the great outdoors, whiling away afternoons fishing, hiking, and reading old books.

Mike's interests include fishing, hiking, and... FALCONRY

Mike earned a degree in Computer Science from Yale University, where he met SilviaTerra founders Zack and Max. At the time, Mike was channeling his love of the outdoors into a website that helped people find great hunting guides. After graduating, Mike worked as a software developer for Redfin - a technology-driven real estate brokerage startup in Seattle.

The Yale Alumni Magazine featured Mike's 
"Mongol Rally" team on the cover - epic!

Immediately prior to joining SilviaTerra, Mike drove ten thousand miles from London to Mongolia in the Mongol Rally. His team - the "Bad Latitudes" - was the largest team in event history. After countless flat tires, car breakdowns, and narrowly-avoided international incidents, they successfully made it across to the finish line.

At SilviaTerra, Mike will be working hard to make us faster, better, and stronger.  Keep an eye out for lots of improvements, speedups, and new features.  Welcome aboard Mike!

2017 Q1 All-Hands

Every quarter, the fully remote SilviaTerra team assembles from all corners of the world, rents a house, and spends a week building new features and planning future conquests.

The SilviaTerra squad manages to not fall into any canals
Thanks to Travis Pond for his services as the SilviaTerra team picture guy!

We just wrapped up our 2017 Q1 All Hands in The Hague, Netherlands.  This was our first All-Hands meeting outside of the US and it was a great success.  No one fell into any canals, although apparently about a car a week does in the Netherlands!  In addition to the sightseeing and delicious Dutch food, we made major technical progress on:

  • The upcoming version of Plot Hound with customizable data entry
  • Improvements to CruiseBoost for both large and small properties
  • Change detection using a variety of imagery platforms

If that sounds like a good time to you, we'd love to meet you!  Drop us a line at

Stumpage Value and Product Groups for Merch Specs

We're dedicated to the foresters we serve and we're always investing in Plot Hound and Canopy to make them better and more useful tools.  Since we launched our merch specs system in late 2015, we have had many great conversations with foresters across America who use Plot Hound and Canopy as their main cruising platform.  The top two requests we heard were product groups and stumpage pricing.  Starting today, both of those features are live!

The "Product Group" field allows you to assign each of your products to a product group.  If you have a volume subscription, your volumes will now be summarized by both product and product group.  This works great for cases where you want rollups of general product groups like Sawtimber that contain distinct products like Pine Saw and Hardwood Saw.

You can also now assign a stumpage value for each of your products.  If you are signed up for one of our volume reporting service, your reports will include a summary of stumpage value by product and product group.

We've also invested in some performance engineering on the backend, so the merch specs page is faster than ever. Our mission is always to save you time on the computer you can spend more time in the woods and with your clients.

We are always looking for feedback on how we can improve Canopy and Plot Hound.  Feel free to drop us a line at if you have any suggestions or need any help.

Revamped Cruise Setup

We have just deployed updates to Canopy that give you more control when setting up your cruise!  We have had a lot of requests for new features and we have answered the call!  Our new updates offer you the ability to set up hexagonal, square, and rectangular grid types as well as random points (1).  Rectangular grids offer the ability to manually set the distances between points and lines.  Now you can set up any grid spacing you want!  Running lines north and south isn’t always the most efficient layout, so we have also built in a grid rotation feature (6).  If you are concerned about edge plots (and willing to accept the sampling bias associated with avoiding edge ), we offer you the ability to set an inner bounds buffer where plots won't be allocated (2).  As an example if you don't want to take any plots within 25 feet of the stand boundary, just set the inner bounds buffer to 25.  Simple as that.


The overall process is slightly different from the previous version, where we would use the statistical parameters you entered to automatically create a grid.  Now, instead of automatically setting up a grid, we calculate the number of plots you need based on the statistical parameters and display it above the plots per stand box (3).  You then enter the number of plots you would like in the plots per stand box (4).  If you have a plot density you want to use, say 1 plot per 2 acres, you can enter that in the plots per acre input box (5) to create the grid.  After you set your inputs, just click on 'Create
Grid' (7).

Top Left - Hexagonal Grid, Top Right - Square Grid,
Middle Left - Rectangular Grid, Middle Right - Random Point Grid,
Lower Left - Rotated Grid, Lower Right - Grid with an inner buffer applied

 You may notice that sometimes you don't get back the exact number of plots you requested.  When laying out grids it is nearly impossible to adjust the spacing so that you come up with the correct number of plots 100% of the time.  Our past system worked around this by creating more than enough plots and then randomly dropping some until the right number was achieved.  This worked well, but sometimes left weird holes in your grid, and we thought we could do better.  This time around we chose not to drop any plots and tried to get the plot count as close as we could. If you are not satisfied with the grid you can simply click 'Create Grid' again, and let the layout algorithm try again.

We are always looking for feedback on how we can improve our system.  Feel free to drop us a line at if you have any suggestions or need any help.
