The MAPSS Annual Meeting is scheduled for Tuesday, March 18th, 2014 at the Wells Conference Center at the University of Maine in Orono. Download the Agenda and the Registration form.


The proposal from the MAPSS Technical Committee for adoption of the Connotative Soil Survey (CSS) and accompanying Explanation and Usage Guide should be carefully reviewed prior to the Annual Meeting of March 18th, 2014.

  • The Connotative Soil Survey and accompanying Explanation and Usage Guide are an “additional option” or “optional addition”, to be added to the current MAPSS Guidelines;

  • And that the current MAPSS Guidelines for Order I mapping ("High Intensity Soil Surveys"; i.e., Class A, B, C, D) will not change;

  • And the Order I mapping ("High Intensity Soil Surveys"; i.e., Class A, B, C, D) map will still need to be performed.

Please view the comparison chart for the two mapping styles for additional details.


M.A.W.S. Annual Meeting is scheduled for Wednesday, March 26th, 2014, at Thorne Hall, Bowdoin College, Brunswick.

2013

On Thursday, September 26th, plan on attending the MASE Field Day at Pineland Farms in New Gloucester, Maine. Backhoe-dug soil pits will be available for morning inspection, followed by an afternoon discussion.


October 11-13th: 3 days, 17 individual, day-long field trips, including bedrock, glacial, pedology, archaeology, and mining trips in the Katahdin region. Pre-registration is required at New England Intercollegiate Geological Conference.


Minimum size map units for wetland delineation: The following guidance is provided by U.S. ACOE Senior Project Manager Jay Clement. It evolved from the panel discussion at the September 4th, 2013 MAPSS field conference at Mt. Blue State Park. Jay Clement can be reached at the Maine Project Office, (207) 623-8367.

  • "Getting back to you and the group as promised on the question about mapping protocols. After discussing the question with Ruth Ladd and Paul Minkin at our MA headquarters, they confirm that there is no definitive guidance to fall back on in the '87 Corps Manual or the Regional Supplement. Similarly, there isn't any informal guidance to fall back on. And at least the New England states appear to all have variable requirements as to the size wetland that gets mapped."

  • "So some best professional judgment and common sense has to prevail here. Is the wetland just an isolated pocket or is it part of some larger pit/mound landscape. If it's the latter, the regional supplement does offer guidance as to when areas are wetlands and when they're not. A delineator could therefore make a call that a pit/mound landscape wasn't a wetland even though there might be 'pockets' of hydric soil, hydrology indicators, and wetland plants. Your map/plan would reflect that."

  • "But when all you're dealing with is a traditional landscape that happens to have some wetland 'pockets', there is technically no minimum threshold for mapping if an area meets all 3 parameters. Many of these folks are already identifying and mapping vernal pools or potential vernal pools down to pretty small sizes. Wetland mapping really shouldn't be much different. How it appears on a plan will undoubtedly be a function of the plan's scale. On a small scale map, small wetlands, drainages, vernal pools, etc will probably only be represented by a symbol, a dashed line (drainage), or a point. A larger scale map lends itself to greater detail in terms of depicting an actual boundary."

  • "However you make the call, document, document, document (so that third parties understand why you determined what you did). And when in doubt, contact the Corps and the DEP."

The Janet Engle Cormier Memorial Scholarship Committee voted on March 27th, 2013 to split the $1,000 award to two deserving candidates, Aaron Englander and Cayce Salvano. UMaine-Orono plans to have an awards ceremony on Wednesday, April 17 at the University’s Fogler Library, and MAPSS President Don Phillips will hand out $500 checks to each of them at the ceremony.


Following up on members' questions during Tom Peragallo's presentation at the 2013 Annual Meeting, Ruth Ladd from US ACOE gives this guidance for using the New England Hydric Soil Indicators
'Chapter 5 (of the "Supplement" manual, on p.114: "In general, wetland determinations on difficult or problematic sites must be based on the best information available to the field inspector, interpreted in light of his or her professional experience and knowledge of the ecology of wetlands in the region."
The NE Indicators document is one type of "best information" that can be used to support how a practitioner addresses a problem soil. It is not the only thing.'

Changes to the MAPSS Guidelines: The Membership voted to suspend the section on Oxyaquic Conditions, pending field trials set to begin during the early summer of 2012. These field studies will evaluate the relationship between drainage class & hydrology, redoximorphic features indicative of saturation, and timing of the growing season.

"SOIL WETNESS Soil wetness refers to the duration, depth and oxidation state of a seasonal high water table [AND]. There are two kinds of seasonal water tables which soil mappers should identify when working in the field. One is associated with a water table that becomes at least partially devoid of oxygen resulting in the formation of redoximorphic features. These soils are mapped according to soil drainage classes as described below. The other kind is associated with a water table that does not become devoid of oxygen so that redoximorphic features do not form. These soils however have other morphological indicators of soil wetness. They should be mapped according to the discussion of Soils With Oxyaquic Conditions below. Soils With Oxyaquic Conditions Some soils have a seasonal high water table which does not result in the development of redoximorphic features because they do not become devoid of oxygen. Since soils with oxygenated water react similarly to those that have an anaerobic water table for most uses and management purposes, it is important to identify and map them. These soils are typically located in either cool climates (coastal, high elevations or northern parts of the State) on long sloping landforms, particularly those formed by lodgment till or where the slope levels out at the base of a long slope. They are most common where there are both cool temperatures and wetter positions in the landscape. Cool temperatures reduce microbial activity and long sloping landforms provide for oxygenated water. These soils may have redoximorphic features in dense parent material but commonly lack them in the soil horizons above the pan. In order to determine the depth to the seasonal high water table it is necessary to look for other morphological indicators of wetness within the soil and take into consideration a number of other site-related factors. These soils should be mapped as variants of the soil series that they are most similar to and would react like, for use and management. For instance, if a soil classifies as being moderately well drained according to depth and type of redoximorphic features, but has evidence of oxyaquic conditions consistent with the depth to a seasonal high water table of a somewhat poorly drained soil, it should be mapped as a somewhat poorly drained variant of the wetter soil series. Indicators of Soils With Oxyaquic Conditions Soils with oxyaquic conditions commonly (but not always):

  • 1. are in slight to strongly concave positions in the landscape but may be on a uniform slope.
  • 2. have a very stony to rubbly surface that may be covered with organic duff.
  • 3. have vegetation that is shallow rooted but not because of dense till, bedrock, very coarse textured soil horizons, or a seasonal water table with redoximorphic features present.
  • 4. have thickened organic horizons as compared to better drained soils in the vicinity
  • 5. have an A or thickened A horizon where better drained soils in the vicinity do not have an A or have a thin A horizon.
  • 6. are less well developed than better drained soils in the vicinity. Commonly, they will classify as Inceptisols while better drained soils in the vicinity will classify as Spodosols or have spodic properties.
  • 7. have evidence of organic matter streaking or different shades of olive and brown in the B horizon (poly value and/or poly chromatic).
  • 8. have vegetation that is hydrophytic or the vegetation is upland but has evidence of stress such as tree roots growing along the ground surface, multi- stems and/or buttressing.
  • 9. have a large contributing (upslope) watershed to create the groundwater table and for the hydraulic gradient necessary to push it along."

The MAPSS Annual Meeting was held on Friday, March 16th at University of Southern Maine - Portland campus. Meeting Agenda and registration form should be downloaded. The registration deadline is MARCH 7th.


The MAPSS Technical Committee proposed the following changes to the MAPSS Drainage Key, which were approved by the Memberhsip at the Annual Meeting:

  1. Under PD criteria, “…a Bh or Bhs horizon that is value 3 or less and chroma 3 or less, ….” [changing from chroma 2 to chroma 3]

  2. Adopting a new format for PD and VPD that follows the style of the keys found in Keys to Soil Taxonomy, Eleventh Edition, 2010.

  3. Removing the “p” from “Ap” horizon (an “A” horizon by definition includes Ap horizons and all other subordinate distinctions)

  4. Converting inch measurements to metric as the primary standard, but still retaining the inches in parentheses.

Maine Catena Key Update (spring, 2008)

  • Boothbay is now limited to MWD
  • Pushaw added as an aquept (SPD) to the Boothbay catena
  • Ricker now limited to cryic areas
  • Knob Lock replaces Ricker in frigid areas
  • Moosabec replaces Waskish as sphagnofibrists in the Northeast
  • Meadowsedge replaces Rifle as Euic Frigid Typic Haplohemists in the Northeast
  • Do NOT use the Peru soil series in the Marlow catena; use Dixfield
  • Do NOT use any mesic soil series in Maine
  • In the old soil surveys, Buxton soils on a B-slope are now Lamoine soils



MOOSABEC soil series adopted in Maine

The MOOSABEC series has replaced the Waskish series. These are very poorly drained organic soils. For more information, visit the links in the left navigation column SOIL DATA and head to the OSD descriptions.

KNOB LOCK soil series adopted in Maine

"The Knob Lock series consists of very shallow and shallow, well drained to excessively drained organic soils on mountains and hills. They formed in thin organic deposits underlain in most places by a very thin mineral horizon over bedrock. TAXONOMIC CLASS: Dysic, frigid Lithic Udifolists" (Official Series Description)
Note that this soil series is in the frigid temperature regime. Ricker soils are now limited to the cryic temperature regime.
