      This Amendment No. 2 to Schedule 13D amends and supplements the Schedule

transaction described in Item 4 below, as it relates to MSDW, MSIM and MSRESSI
(MSRESSI, together with MSDW and MSIM, the "Reporting Persons").

      The class of equity securities to which this statement relates is the
common shares of beneficial interest, $.01 par value per share ("Common
Shares"), of Ramco-Gershenson Properties Trust, a Maryland real estate
investment trust (together with its predecessors, the "Issuer"). The principal
executive offices of the Issuer are located at 27600 Northwestern Highway, Suite
200, Southfield, Michigan.

ITEM 2.     IDENTITY AND BACKGROUND

      Item 2 is hereby amended and supplemented by adding the following:

      (a) This Schedule 13D is being filed jointly on behalf of the following
persons (collectively, the "Reporting Persons"):

            (1)  Morgan Stanley Dean Witter & Co., a Delaware corporation;

            (2)  Morgan Stanley Investment Management Inc., a Delaware
                 corporation; and

            (3)  MS Real Estate Special Situations, Inc., a Delaware
                 corporation.

      (c) Set forth in Schedule A is the name, citizenship, business or

------------------------------                       ---------------------------

address of any corporation or other organization in which such occupation or
employment is conducted, of each of the directors and executive officers of
MSRESSI, as of the date hereof.

      (d) None of the Reporting Persons, nor, to the knowledge of the Reporting
Persons, any of the other persons listed on Schedules A, B and C attached
hereto, has been convicted in a criminal proceeding in the past five years
(excluding traffic violations or similar misdemeanors).

      (e) During the past five years, none of the Reporting Persons, nor, to the
knowledge of the Reporting Persons, any of the other persons listed on Schedules
A, B and C attached hereto, was a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction as a result of which such person
was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to such laws. ITEM

ITEM 4.    PURPOSE OF TRANSACTION.

      Item 4 is hereby amended and supplemented by adding the following:

      (a) The purpose of this filing is to report that the Reporting Persons
have ceased to be beneficial owners of more than 5% of the Common Shares. On
March 14, 2002 the Issuer, MSRESSI and the selling shareholders entered into a
Stock Redemption Agreement ("Agreement") by which the Issuer would redeem from
MSRESSI and the other selling shareholders 1,200,000 shares of Series A
Convertible Preferred Shares ("Preferred Shares"), par value $0.01 per share
(representing 1,714,286 Common Shares) for $22.1429 per share, subject to market
price adjustments and other conditions described in the Agreement attached as
Exhibit 7. On May 20, 2002, the selling shareholders tendered shares
certificates representing 1,200,000 Preferred Shares to the Issuer in exchange
for payment in full therefor, $26,571,428.57 in the aggregate. As a consequence,
as of May 20, 2002, MSDW, MSIM and MSRESSI ceased to be reporting Persons for
the purpose of Rule 13d-1.

      Except as described above, as of the date of this Amendment No. 2 to
Schedule 13D, the Reporting Persons have no present plans or proposals of a type
requiring disclosure under Item 4 of Schedule 13D.

      MSDW is filing solely in its capacity as parent company and indirect
beneficial owner of securities held by its business units.

ITEM 5.    INTEREST IN SECURITIES OF THE ISSUER.

      Item 5 is hereby amended and supplemented by adding the following:

------------------------------                       ---------------------------

------------------------------                       ---------------------------

      As of the date of this filing, MSDW and MSRESSI, for the purpose of Rule
13d-3 promulgated under the Exchange Act, beneficially own 7,400 Common Shares
representing approximately 00.104% of the outstanding Shares (based on 7,088,926
Common Shares reported by the Company as outstanding on March 13, 2002 in its
report on Form 10-K for the fiscal year ended December 31, 2001);

      The response to Item 4 is incorporated herein by reference.

ITEM 6.     CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
            RESPECT TO SECURITIES OF THE ISSUER.

      Item 6 is hereby amended and supplemented by adding the following:

      The response to Item 4 is incorporated herein by reference.
