The Fund invests globally and has exposure to emerging and developed markets. The Fund may invest in companies of any size, and seeks diversification by country and economic sector. The Fund generally will invest at least 40% of its net assets in foreign companies. Foreign companies are those that either maintain their principal place of business outside of the United States, have their securities traded on non-U.S. exchanges or were formed under the laws of non-U.S. countries. Foreign companies may include companies doing business in the United States but meet the general criteria of a foreign company described above. The Fund will invest in at least three different countries outside of the United States. The Fund's foreign holdings may include companies domiciled in emerging markets as well as companies domiciled in developed markets. There is no limit to the percent of the Fund's foreign holdings that may be invested in either emerging or developed markets and therefore the Fund may be invested entirely in companies from emerging markets. A security will be sold within a reasonable period of time if the company no longer meets the Advisor's environmental evaluation criteria or if the company no longer meets the Advisor's minimum financial standards.
Risk [Heading]	rr_RiskHeading	Principal Investment Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	There is a risk that you could lose all or a portion of your investment in the Fund. The following principal risks can affect the value of your investment: ·  Equity Risk - Common stocks are susceptible to general stock market               fluctuations and to volatile increases and decreases in value. ·  General Market Risk: The market price of a security may fluctuate, sometimes      rapidly and unpredictably. These fluctuations may cause a security to be worth    less than its cost when originally purchased or less than it was worth at an      earlier time. ·  Small- and Medium-Sized Company Risk: Investing in securities of small- and       medium-sized companies, even indirectly, may involve greater volatility than      investing in larger and more established companies. ·  Management Risk: The Advisor may fail to implement the Fund's investment          strategies and meet its investment objective. ·  Foreign Securities and Emerging Markets Risk: Foreign securities involve          increased risks due to political, social and economic developments abroad,    as well as due to differences between U.S. and foreign regulatory practices.    These risks are enhanced in emerging markets. ·  Environmental Policy Risk: The Fund's environmental sustainability policy         could cause it to underperform compared to similar funds that do not have    such a policy. Accordingly, the Fund may forego opportunities to buy certain           securities when it might otherwise be advantageous to do so, or may sell          securities for environmental reasons when it might be otherwise disadvantageous    for it to do so.

SUMMARY SECTION

Investment Objective

The Portfolio 21 Global Equity Fund (the "Fund") seeks long-term capital growth.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees Portfolio 21 Global Equity Fund	Class R	Class I
Redemption Fee (as a percentage of amount redeemed within 60 days of purchase)	2.00%	2.00%

Annual Portfolio Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses Portfolio 21 Global Equity Fund		Class R	Class I
Management Fee		0.95%	0.95%
Distribution and Service (12b-1) Fee		0.25%	none
Other Expenses		0.27%	0.22%
Total Annual Fund Operating Expenses	[1]	1.47%	1.17%

Example

This Example is intended to help you compare the costs of investing in the Fund
with the cost of investing in other mutual funds. The Example assumes that you
invest $10,000 in the Fund for the time periods indicated and then redeem all
of your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same (taking into account the contractual Expense Caps only in the
first year).

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example Portfolio 21 Global Equity Fund (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Class R	150	465	803	1,757
Class I	119	372	644	1,420

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate
may indicate higher transaction costs and may result in higher taxes when Fund
shares are held in a taxable account. These costs, which are not reflected in
annual portfolio operating expenses or in the example, affect the Fund's
performance. During the most recent fiscal year, the Fund's turnover rate was
28% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests primarily in common stocks of companies that the Advisor
believes are leaders in managing environmental risks and opportunities,
have above average growth potential, and are reasonably valued. Under normal
market conditions, at least 80% of the Fund's net assets (plus any borrowings
for investment purposes) will be invested in equity securities. The Fund
invests globally and has exposure to emerging and developed markets. The Fund
may invest in companies of any size, and seeks diversification by country and
economic sector.

The Fund generally will invest at least 40% of its net assets in foreign
companies. Foreign companies are those that either maintain their principal
place of business outside of the United States, have their securities traded
on non-U.S. exchanges or were formed under the laws of non-U.S. countries.
Foreign companies may include companies doing business in the United States
but meet the general criteria of a foreign company described above. The Fund
will invest in at least three different countries outside of the United States.

The Fund's foreign holdings may include companies domiciled in emerging markets
as well as companies domiciled in developed markets. There is no limit to the
percent of the Fund's foreign holdings that may be invested in either emerging
or developed markets and therefore the Fund may be invested entirely in companies
from emerging markets.

A security will be sold within a reasonable period of time if the company no
longer meets the Advisor's environmental evaluation criteria or if the company
no longer meets the Advisor's minimum financial standards.

Principal Investment Risks

There is a risk that you could lose all or a portion of your investment in the
Fund. The following principal risks can affect the value of your investment:

·  Equity Risk - Common stocks are susceptible to general stock market           
   fluctuations and to volatile increases and decreases in value.

·  General Market Risk: The market price of a security may fluctuate, sometimes  
   rapidly and unpredictably. These fluctuations may cause a security to be worth
   less than its cost when originally purchased or less than it was worth at an  
   earlier time.

·  Small- and Medium-Sized Company Risk: Investing in securities of small- and   
   medium-sized companies, even indirectly, may involve greater volatility than  
   investing in larger and more established companies.

·  Management Risk: The Advisor may fail to implement the Fund's investment      
   strategies and meet its investment objective.

·  Foreign Securities and Emerging Markets Risk: Foreign securities involve      
   increased risks due to political, social and economic developments abroad,
   as well as due to differences between U.S. and foreign regulatory practices.
   These risks are enhanced in emerging markets.

·  Environmental Policy Risk: The Fund's environmental sustainability policy     
   could cause it to underperform compared to similar funds that do not have
   such a policy. Accordingly, the Fund may forego opportunities to buy certain       
   securities when it might otherwise be advantageous to do so, or may sell      
   securities for environmental reasons when it might be otherwise disadvantageous
   for it to do so.

Performance

The following performance information provides some indication of the risks of
investing in the Fund. The bar chart below illustrates how the Fund's Class R
shares total returns have varied from year to year. The table below illustrates
how the Fund's average annual total returns for 1, 5, and 10-year periods
compare with that of a broad-based securities index and an additional index
provided to offer a broader market perspective. The Fund's past performance,
before and after taxes, is not necessarily an indication of how the Fund will
perform in the future. Updated performance information is available on the
Fund's website at www.portfolio21.com.

Class I shares of the Fund commenced operations on March 30, 2007. Performance shown
for Class I shares for periods prior to its inception reflects the performance of
Class R shares, adjusted to reflect Class I expenses.

After-tax returns are calculated using the historical highest individual federal
marginal income tax rates and do not reflect the impact of state and local taxes.
Actual after-tax returns depend on your situation and may differ from those shown.
Furthermore, the after-tax returns shown are not relevant to those who hold their
shares through tax-deferred arrangements such as 401(k) plans or Individual
Retirement Accounts ("IRAs"). The "Return After Taxes on Distributions and Sale
of Fund Shares" may be higher than the return figures because when a capital loss
occurs upon redemption of fund shares, a tax deduction is provided that benefits
the investor.

[1] Portfolio 21 (the "Advisor") has contractually agreed to reduce its fees and/or pay the Fund's expenses (excluding acquired fund fees and expenses, interest expense in connection with investment activities, taxes and extraordinary expenses) in order to limit Total Annual Portfolio Operating Expenses for Class R shares and Class I shares of the Fund to 1.50% and 1.20%, respectively, of each class' average net assets (the "Expense Caps"). The Expense Caps will remain in effect until at least October 31, 2014. The Agreement may be terminated at any time by the Board upon 60 days' written notice to the Advisor, or by the Advisor with the consent of the Board. The Advisor may request recoupment for management fee waivers and/or Fund expense payments made in the prior three fiscal years.
