Hardware/Software

The MassACORN website currently runs on a HP Proliant Windows 2003 Server using Microsoft's Internet Information Server 6.x (specifications below). Because of University of Massachusetts' computer security requirements, we installed Computer Associates Arcserve 9 firewall software. The server has the API version of PHP and the MySQL database server installed. We administer the MySQL databases using PHP MyAdmin. PHP and MySQL provide the backend for the phpBB message board and the online survey. MapServer powers the map serving application. We use Dreamweaver to edit and maintain the website, and the HP Proliant server gets backed up nightly.

Description of the ACORN Web

The ACORN web currently occupies about 200MB of disk space, but the 1-meter resolution orthophoto data that MapServer uses to render maps of the 40-mile by 48-mile MassACORN study area take up an additional 12 GB of disk storage. The web uses a CSS style sheet for consistent formatting of pages and a simple javascript to generate navigation bars.

What does it cost to build an ACORN website?

Although ACORN currently runs on a Windows platform, it could just as easily run on the Open Source (OS) Apache (http://www.apache.org/) server using the Linux operating system. The OS Linux, Apache, PHP, MySQL,MapServer and phpBB software are available at no cost and can be easily downloaded from the Internet. A competent technician could install and configure the necessary software in a day or two.

The most technically challenging part of duplicating the ACORNwebsite involves processing the geographic data for MapServer. It took about 140 hours to process the data and get the MapServer application functioning. Assuming the geographic data are readily available, building the MapServer application for an area the size of the MassACORN study area would probably cost $5,000 to $7,000 if outsourced. Alexander Stepanov, part of the MassACORNteam, did the MapServer development.

Developing the content for an ACORN website and constructingthe web's pages can take considerable time, but once the site is running anyonewith basic web skills can update and maintain the site. Jennifer Fish developed most of the content with input from Dave Kittredge and Paul Catanzaro. Charlie Schweik and Alexander Stepanov provided technical assistance.

Purchasing a suitable server could cost from a few hundred to a few thousand dollars depending on how much traffic is expected. The current ACORN server would cost at the low end of this range. High bandwidth Internet service (T1 1.5MB) costs about $500 per month. Hosting MassACORN on a dedicated server at an Internet Service provider (http://www.crystaltech.com/dedicated.htm) can be done for as little as $80 per month.

Funding

ACORN is supported by the National Research Initiative of theUSDA Cooperative State Research, Education and Extension Service, grant number 2006-55101-16564.

Organized/Maintained

ACORN is currently maintained by the ACORN team in the Department of Natural Resources Conservation at the University of Massachusetts-Amherst.

ACORN is organized by David Kittredge, Charlie Schweik, Jennifer Fish, Paul Catanzaro, and Alexander Stepanov of the Department of Natural Resources Conservation at the University of Massachusetts Amherst; Tom Stevens and Mike LeVert of the Department of Resource Economics at the University of Massachusetts - Amherst; in cooperation with The State of Massachusetts' Department of Conservation and Recreation's Bureau of Forestry, with spatial data generously provided by MassGIS and The Nature Conservancy and wildlife photographs provided by Bill Byrne and Lori Cookman of MassWildlife.

MapServer Metadata

Information about the data used in MapServer:

Majority of the data currently used in ACORN MA MapServer were obtained from the MassGIS. MassGIS and the State of Massachusetts make no representations of any kind, including but not limited to the warranties of merchantability or fitness for a particular use, nor are any such warranties to be implied with respect to the data.  It is possible to draw maps with the ACORN MA MapServer that juxtapose very accurate data and less accurate data. Please examine the table below before drawing conclusions about the accuracy of any map you create! Also please refer to metadata provided by MassGIS.

The Nature Conservancy Layer

Large Forest Blocks

Large forest blocks are areas bounded by features from the 1:100k US Census Bureau's TIGER line dataset, such as roads, railroads, major utility lines, and major shorelines.  The bounding block feature types were chosen due to their ecological impact on biodiversity in terms of fragmentation, dispersion, edge-effects, and invasion of alien species.

Large forest blocks represent areas whose size and natural condition allow for the maintenance of ecological processes, viable occurrences of matrix forest communities, embedded large and small patch communities, and embedded species populations. The goal within large, or matrix, forest blocks was to identify viable examples of the dominant forest types that, if protected as forest cores within the blocks and allowed to regain their natural condition, would serve as critical source areas for all species requiring interior forest conditions or associated with the dominant forest types.

Interior Forest Habitat

The interior forest habitat dataset was created by the Division of Fisheriesand Wildlife of the Massachusetts Department of Fish and Game.

Interior forest habitat represents patches of unfragmented forest within forested areas of the Commonwealth of Massachusetts. These polygons were taken directly from 1999 land use data, and buffered away from roads and develop-related land uses; the result is the interior patches.

The dataset was developed to facilitate the selection of forest reserves in Massachusetts as part of Green Certification by the Forest Stewardship Council on lands owned by Massachusetts state agencies. Users should bear in mind that these data represent land use current as of 1999.

Fragmenting buffer widths were based partially on done by The Nature Conservancy, Boston Office according to work by:
Forman, R.T.T., and R.D. Deblinger. 2000. The Ecological Road-Effect Zoneof a Massachusetts (U.S.A.) Suburban Highway. ConservationBiology 14:36-46.
